Animal locomotion
Animal locomotion, in ethology, is any of a variety of movements or methods that animals use to move from one place to another. Some modes of locomotion are (initially) self-propelled, e.g., running, swimming, jumping, flying, hopping, soaring and gliding. There are also many animal species that depend on their environment for transportation, a type of mobility called passive locomotion, e.g., sailing (some jellyfish), kiting (spiders) and rolling (some beetles and spiders). Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators. For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms.
Terrestrial locomotion
Terrestrial locomotion has evolved as animals adapted from aquatic to terrestrial environments. Locomotion on land raises different problems than that in water, with reduced friction being replaced by the effects of gravity. There are three basic forms of locomotion found among terrestrial animals  Movement on appendages is the most common form of terrestrial locomotion, it is the basic form of locomotion of two major groups with many terrestrial members, the vertebrates and the arthropods. Important aspects of legged locomotion are posture (the way the body is supported by the legs), the number of legs, and the functional structure of the leg and foot.
Undulatory locomotion
Undulatory locomotion is the type of motion characterized by wave-like movement patterns that act to propel an animal forward. Examples of this type of gait include crawling in snakes, or swimming in the lamprey. Although this is typically the type of gait utilized by limbless animals, some creatures with limbs, such as the salamander, choose to forgo use of their legs in certain environments and exhibit undulatory locomotion. This movement strategy is important to study in order to create novel robotic devices capable of traversing a variety of environments. In limbless locomotion, forward locomotion is generated by propagating flexural waves along the length of the animal's body.
Pinniped
Pinnipeds, commonly known as seals, are a widely distributed and diverse clade of carnivorous, fin-footed, semiaquatic marine mammals. They comprise the extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals). There are 33 extant species of pinnipeds, and more than 50 extinct species have been described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular evidence supports them as a monophyletic lineage (descended from one ancestral line).
Snake
Snakes are elongated, legless, carnivorous reptiles of the suborder Serpentes. Like all squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws. To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca.
Bio-inspired robotics
Bio-inspired robotic locomotion is a fairly new subcategory of bio-inspired design. It is about learning concepts from nature and applying them to the design of real-world engineered systems. More specifically, this field is about making robots that are inspired by biological systems. Biomimicry and bio-inspired design are sometimes confused. Biomimicry is copying the nature while bio-inspired design is learning from nature and making a mechanism that is simpler and more effective than the system observed in nature. Biomimicry has led to the development of a different branch of robotics called soft robotics.
Fin and flipper locomotion
Fin and flipper locomotion occurs mostly in aquatic locomotion, and rarely in terrestrial locomotion. From the three common states of matter — gas, liquid and solid, these appendages are adapted for liquids, mostly fresh or saltwater and used in locomotion, steering and balancing of the body. Locomotion is important in order to escape predators, acquire food, find mates and bury for shelter, nest or food. Aquatic locomotion consists of swimming, whereas terrestrial locomotion encompasses walking, 'crutching', jumping, digging as well as covering. Some animals such as sea turtles and mudskippers use these two environments for different purposes, for example using the land for nesting, and the sea to hunt for food.

Dryas iulia
Dryas iulia (often incorrectly spelled "julia"), commonly called the Julia butterfly, Julia heliconian, the flame, or flambeau, is a species of brush-footed butterfly (known as Nymphalidae). The sole representative of its genus Dryas, it is native from Brazil to southern Texas and Florida, and in summer can sometimes be found as far north as eastern Nebraska. Over 15 subspecies have been described. Its wingspan ranges from 82 to 92 mm, and it is colored orange (brighter in male specimens) with black markings; this species is somewhat unpalatable to birds and belongs to the "orange" Batesian mimicry complex.
Running
Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion. A characteristic feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity.
Level and incline running
Terrestrial locomotion by means of a running gait can be accomplished on level surfaces. However, in most outdoor environments an individual will experience terrain undulations requiring uphill running. Similar conditions can be mimicked in a controlled environment on a treadmill also. Additionally, running on inclines is used by runners, both distance and sprinter, to improve cardiovascular conditioning and lower limb strength. One complete gait cycle is defined as beginning when one foot comes into contact with the ground and continuing until that same foot contacts the ground again. The gait cycle can be further broken down into a number of component parts.
NEMA connector
NEMA connectors are power plugs and receptacles used for AC mains electricity in North America and other countries that use the standards set by the US National Electrical Manufacturers Association. NEMA wiring devices are made in current ratings from 15 to 60 amperes (A), with voltage ratings from 125 to 600 volts (V). Different combinations of contact blade widths, shapes, orientation, and dimensions create non-interchangeable connectors that are unique for each combination of voltage, electric current carrying capacity, and grounding system. NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on commonplace domestic electrical equipment, and NEMA 5-15R is the standard 15 A electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada ("CSA C22.2 No.
Elephant
Elephants are large mammals of the family Elephantidae and the order Proboscidea. Three species are currently recognized: the African bush elephant ("Loxodonta africana"), the African forest elephant ("L. cyclotis"), and the Asian elephant ("Elephas maximus"). Elephants are scattered throughout sub-Saharan Africa, South Asia, and Southeast Asia. Elephantidae is the only surviving family of the order Proboscidea; other, now extinct, members of the order include deinotheres, gomphotheres, mammoths, and mastodons. All elephants have several distinctive features, the most notable of which is a long trunk or proboscis, used for many purposes, particularly breathing, lifting water, and grasping objects.
Aircraft in fiction
Aircraft in fiction covers the various real-world aircraft that have made significant appearances in fiction over the decades, including in books, films, toys, TV programs, video games, and other media. These appearances spotlight the popularity of different models of aircraft, and showcase the different types for the general public. The first aviation film was the 1911 William J. Humphrey–directed two-reeler, "The Military Air-Scout", shot following an Aero Club of America flying meet at Long Island, New York, with Lt. Henry Arnold doing the stunt flying. "Arnold, who picked up 'a few extra bucks' for his services, became so excited about movies that he almost quit the Army to become an actor."
Australia at the Winter Olympics
Australia first competed in the Winter Olympic Games in 1936 in Garmisch-Partenkirchen, and has participated in every games since, with the exception of the 1948 Games in St. Moritz. In the early years, Australia's athletes did poorly; only two athletes placed in the top half of their events before 1976, while the vast majority placed in the bottom quarter, including some who finished last. This lack of success was attributed to the Australian culture, climate and lack of snow, as well as the lack of support for the athletes—sports administrators regarded investment in winter sports as futile. After the appointment of Geoff Henke—who had been unable to compete in 1956 after the administrators neglected to endorse his ice hockey team's application—as team manager in 1976, the results slowly began to improve, and by the 1990s, some Australians were regarded as medal prospects.

Gait (human)
Human gait refers to locomotion achieved through the movement of human limbs. Human gait is defined as bipedal, biphasic forward propulsion of center of gravity of the human body, in which there are alternate sinuous movements of different segments of the body with least expenditure of energy. Different gait patterns are characterized by differences in limb movement patterns, overall velocity, forces, kinetic and potential energy cycles, and changes in the contact with the surface (ground, floor, etc.). Human gaits are the various ways in which a human can move, either naturally or as a result of specialized training.
Ambling gait
An ambling gait or amble is any of several four-beat intermediate horse gaits, all of which are faster than a walk but usually slower than a canter and always slower than a gallop. Horses that amble are sometimes referred to as "gaited," particularly in the United States. Ambling gaits are smoother for a rider than either the two-beat trot or pace and most can be sustained for relatively long periods of time, making them particularly desirable for trail riding and other tasks where a rider must spend long periods of time in the saddle. Historically, horses able to amble were highly desired for riding long distances on poor roads.
Haha (entertainer)
Ha Dong-hoon (; born on August 20, 1979), better known by his stage name Haha (), is a South Korean singer, variety show host and member of Skull & Haha. He is best known for being in the sitcom, "Nonstop" and for co-hosting two popular variety programs, MBC's "Infinite Challenge" and SBS's "Running Man". He has also hosted his own show, titled "Ya Man TV" on Mnet in 2015. Haha was born on August 20, 1979 in Stuttgart, Baden-Württemberg, West Germany and moved to Seoul, South Korea when he was an infant. His parents are both Korean, with his mother holding a doctorate in psychology, and he has an older sister, Ha Juri () who is a pianist, also with a doctorate.
Parkinsonian gait
Parkinsonian gait (or festinating gait, from Latin "festinare" [to hurry]) is the type of gait exhibited by patients suffering from Parkinson's disease (PD). This disorder is caused by a deficiency of dopamine in the basal ganglia circuit leading to motor deficits. Gait is one of the most affected motor characteristics of this disorder although symptoms of Parkinson's disease are varied. Parkinsonian gait is characterized by small shuffling steps and a general slowness of movement (hypokinesia), or even the total loss of movement (akinesia) in the extreme cases. Patients with PD demonstrate reduced stride length and walking speed during free ambulation while double support duration and cadence rate are increased.
Gait deviations
Gait deviations are nominally referred to as any variation of standard human gait, typically manifesting as a coping mechanism in response to an anatomical impairment. Lower-limb amputees are unable to maintain the characteristic walking patterns of an able-bodied individual due to the removal of some portion of the impaired leg. Without the anatomical structure and neuromechanical control of the removed leg segment, amputees must use alternative compensatory strategies to walk efficiently. Prosthetic limbs provide support to the user and more advanced models attempt to mimic the function of the missing anatomy, including biomechanically controlled ankle and knee joints.
Walking
Walking (also known as ambulation) is one of the main gaits of locomotion among legged animals. Walking is typically slower than running and other gaits. Walking is defined by an 'inverted pendulum' gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the number of limbs—even arthropods, with six, eight or more limbs, walk. The word "walk" is descended from the Old English "wealcan" "to roll". In humans and other bipeds, walking is generally distinguished from running in that only one foot at a time leaves contact with the ground and there is a period of double-support.
Effect of gait parameters on energetic cost
The effect of gait parameters on energetic cost is a relationship that describes how changes in step length, cadence, step width, and step variability influence the mechanical work and metabolic cost involved in gait. The source of this relationship stems from the deviation of these gait parameters from metabolically optimal values, with the deviations due to environmental, pathological, and other factors. In human gait, to travel a particular distance, chemical energy must be expended by the body. This relationship can be expressed by the dimensionless term, cost of transport (COT)., that describes the amount of metabolic energy needed to move a body a unit of distance.

Yeah, running is different to walking too, since one foot is always in contact with the ground when you're walking.
This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.

Freestyle skateboarding tricks
A freestyle skateboarding trick is a trick done on a skateboard while freestyle skateboarding. Some of these tricks are done in a stationary position, unlike many other skateboarding tricks. The keys to a good freestyle contest run are variety, difficulty, fluidity, and creativity. It should also be noted that this is a partial list, and a full list would never be possible, because new tricks and new combinations are always being created. Notes:   1970s skate competitions such as the ones shown in Lords of Dogtown would often have an event to see who could do the most consecutive 360 spins on a skateboard.

Gross motor skill
Gross motor skills are the abilities usually acquired during adulthood and older age as part of a child's motor learning. By the time they reach two years of age, almost all children are able to stand up, walk and run, walk up stairs, etc. These skills are built upon, improved and better controlled throughout early childhood, and continue in refinement throughout most of the individual's years of development into adulthood. These gross movements come from large muscle groups and whole body movement. These skills develop in a head-to-toe order. The children will typically learn head control, trunk stability, and then standing up and walking.
Professional wrestling attacks
Attacking maneuvers are offensive moves in professional wrestling, used to set up an opponent for a submission hold or for a throw. There are a wide variety of attacking moves in pro wrestling, and many are known by several different names. Professional wrestlers frequently give their finishers new names. Occasionally, these names become popular and are used regardless of the wrestler performing the technique. Professional wrestling contains a variety of punches and kicks found in martial arts and other fighting sports; the moves listed below are more specific to wrestling itself. Many of the moves below can also be performed from a raised platform (the top rope, the ring apron, etc.
One Foot in the Grave
One Foot in the Grave is a British BBC television dark comedy sitcom series written by David Renwick. There were six series and seven Christmas specials over an eleven-year period, from early 1990 to late 2000. The first five series were broadcast between January 1990 and January 1995. For the next five years, the show appeared only as Christmas specials, followed by one final series in 2000. The series features the exploits of Victor Meldrew, played by Richard Wilson, and his long-suffering wife, Margaret, played by Annette Crosbie. Wilson initially turned down the part of Meldrew and David Renwick considered Les Dawson for the role, until Wilson changed his mind.

Energy
In physics, energy is the property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton. Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature.
Kinetic energy
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. In classical mechanics, the kinetic energy of a non-rotating object of mass "m" traveling at a speed "v" is . In relativistic mechanics, this is a good approximation only when "v" is much less than the speed of light.
Mass–energy equivalence
In physics, mass–energy equivalence states that anything having mass has an equivalent amount of energy and vice versa, with these fundamental quantities directly relating to one another by Albert Einstein's famous formula:  formula_1  This formula states that the equivalent energy () can be calculated as the mass () multiplied by the speed of light ( = about m/s) squared. Similarly, anything having energy exhibits a corresponding mass given by its energy "divided" by the speed of light squared . Because the speed of light is a very large number in everyday units, the formula implies that even an everyday object at rest with a modest amount of mass has a very large amount of energy intrinsically.
Equipartition theorem
In classical statistical mechanics, the equipartition theorem relates the temperature of a system to its average energies. The equipartition theorem is also known as the law of equipartition, equipartition of energy, or simply equipartition. The original idea of equipartition was that, in thermal equilibrium, energy is shared equally among all of its various forms; for example, the average kinetic energy per degree of freedom in translational motion of a molecule should equal that in rotational motion. The equipartition theorem makes quantitative predictions. Like the virial theorem, it gives the total average kinetic and potential energies for a system at a given temperature, from which the system's heat capacity can be computed.
Potential energy
In physics, potential energy is the energy possessed by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The unit for energy in the International System of Units (SI) is the joule, which has the symbol "J". The term "potential energy" was introduced by the 19th century Scottish engineer and physicist William Rankine, although it has links to Greek philosopher Aristotle's concept of potentiality.
Lagrangian mechanics
Lagrangian mechanics is a reformulation of classical mechanics, introduced by the Italian-French mathematician and astronomer Joseph-Louis Lagrange in 1788. In Lagrangian mechanics, the trajectory of a system of particles is derived by solving the Lagrange equations in one of two forms, either the "Lagrange equations of the first kind", which treat constraints explicitly as extra equations, often using Lagrange multipliers; or the "Lagrange equations of the second kind", which incorporate the constraints directly by judicious choice of generalized coordinates. In each case, a mathematical function called the Lagrangian is a function of the generalized coordinates, their time derivatives, and time, and contains the information about the dynamics of the system.
Schrödinger equation
In quantum mechanics, the Schrödinger equation is a mathematical equation that describes the changes over time of a physical system in which quantum effects, such as wave–particle duality, are significant. The equation is a mathematical formulation for studying quantum mechanical systems. It is considered a central result in the study of quantum systems and its derivation was a significant landmark in developing the theory of quantum mechanics. It was named after Erwin Schrödinger, who derived the equation in 1925 and published it in 1926, forming the basis for his work that resulted in his being awarded the Nobel Prize in Physics in 1933.
