The strength of the force of gravity depends on

• The weight of the objects and their speeds

• The distance of the objects and their speeds

• The masses of the objects and the distance between them

• Mass of the objects and their speeds

The force of gravity gets weaker as the distance between objects increases.

• True

• False

A feather and a bowling ball drop at the same rate on the moon (meaning they will hit the ground at the same time). Why is this?

• Voodoo Magic

• There is no air resistance on the moon (so no air friction)

• The force of gravity is less on the moon

• The force of gravity is greater on the moon

What would have the greater mass? A 35 N sack of bricks on the moon(g=1.62m/s²), or a 200 N sack of feathers on earth(g=9.8m/s²)?

• The sack of bricks

• The sack of feathers

• They would have the same mass
