Gravity Assignement

On Earth, the mass of one of the lunar landing modules used to explore the moon was measured to be about 4,200 kg. The acceleration due to gravity on the moon is about one-sixth that of Earth.

Which arrow, A, B, or C, depicts the force of gravity on the thrown football?

A

Jamal wanted only to test the effect of the free fall and so he put his system in a vacuum to prevent air resistance. In free fall, will the crumpled or flat paper reach the ground first?

Both papers will reach the ground at the same time.

Which factors affect the gravitational force between objects? Check all that apply.

distance between objects masses of the objects

Does this illustration show a sky diver at terminal velocity? Explain your answer.

The illustration shows a sky diver at terminal velocity because the force of gravity is balanced by air resistance.

What did you include in your response? Check all that apply.

The illustration shows terminal velocity. Terminal velocity is reached when the force of gravity is balanced by, or equal to, air resistance.

Suppose for an unexplained reason a star near Earth started shrinking. At what stage is the gravitational force between Earth and the star the greatest?

Stage 1

John throws a baseball from a standing position. Which of the three possible paths will the ball follow?
