# In the given graph the difference between x - coordinate of P and Q is equivalent to-

1. Power
2. Work
3. Potential energy
4. All of the above

Option 2 : Work

## Detailed Solution

The correct answer is option 2) i.e. Work

CONCEPT:

• Work-energy theorem: The work-energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy.

​Work done, $$W = Δ KE = \frac{1}{2}mv^2 - \frac{1}{2}mu^2$$

Where m is the mass of the object, v is the final velocity of the object and u is the initial velocity of the object.

EXPLANATION:

• The x-axis of the given graph has values of kinetic energy.
• The difference in x-coordinates of P and Q is (KEQ - KEPi.e. change in kinetic energy.
• From the work-energy theorem, we know that the change in kinetic energy equals net work done.
• Hence, the difference between x - coordinate of P and Q is work.
