Hallie is experimenting with two balls of the same mass. If Hallie wants to move both balls so that they have an equal change in motion, what should she do?

A
Exert an equal force on both balls.

B
Exert a greater force on the first ball.

C
Exert a greater force on the second ball.

D
None of the above

1 answer

To ensure that both balls have an equal change in motion, Hallie should exert an equal force on both balls. Since they have the same mass, applying the same force will result in the same change in motion (acceleration, according to Newton's second law of motion).

Therefore, the correct answer is:

A Exert an equal force on both balls.
