As the mass of an object increases, the pull of gravity

• Increases

• Decreases

• Stays the same

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

What does the strength of gravity between two objects depend upon?

• Mass & distance
• Mass & weight
• Gravity & inertia
• Inertia & mass

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.
