What force/s were acting on the objects dropped in the air (normal mode)? What force/s was acting on the objects dropped in the vacuum? 

Why was there a difference between the normal mode and the vacuum mode? 

Explain how objects on Earth accelerate compared to objects in the vacuum of space. Be sure to use Newton’s laws of motion to support your explanations. 

The gravitational pull of Jupiter is greater than the gravitational pull of Earth. How would adding a “JUPITER MODE” to the virtual activity change the results of Galileo’s experiment? 

How did your hypotheses match your observations of falling objects in air and in a vacuum?    

Describe other ways you could investigate the acceleration of objects due to gravity.
