931 N

As distance increases, gravitational force ____.

Decreases

As mass decreases, gravitational force ____.

Decreases

Choose True or False. If False, choose the statement that makes it True. On Earth, the force of gravity causes all objects to fall with an acceleration of 8.9 m/s².

False. On Earth, the force of gravity causes all objects to fall with an acceleration of 9.8 m/s².

Choose True or False. If False, choose the statement that makes it True. If a ball and feather are released from a height of 10 meters at the same time, and there is no air friction or other forces, the ball would reach the ground before the feather.

False; If a ball and feather are released from a height of 10 meters at the same time, and there is no air friction or other forces, the ball and feather would reach the ground at the same time.
