Why do we have a stronger gravitational attraction with Earth than the Sun?

• the sun has a larger mass

• the Earth has a larger mass

• we are closer to center of sun

• we are closer to center of Earth

If a feather and a hammer are dropped at the same time on the moon, where there is no atmosphere, which one will hit the ground first?

• Neither, there is no gravity on the moon.

• hammer because it has more mass

• feather because it has less mass

• both will hit at the same time, there is no wind resistance

Which of the following will not change in different gravitational fields?

• weight
• force
• mass
• pounds

Which of these best describes why your weight (on Earth) would change on another planet?

• Dehydration effects on different planets change weight.
• In general, the smaller the planet, the greater weight
• Different planets have different gravitational pulls
• Weight does not change, no matter where you are.

A student drops a bowling ball and an apple from a third-story window. Both objects hit the ground at the same time. From the experiment, the student should conclude that

• the apple weighs more than the bowling ball

• more air friction is acting on the apple than on the bowling ball

• gravity pulls on both objects, causing them to fall at the same time.

What is gravitational force?

• It makes objects at rest start moving.
• It makes objects that are moving stop.
• The force of attraction between two objects.
• It pulls you into space.
