Mass Vs Weight

What two things affect gravity?

• mass and inertia

• mass and distance

• mass and force

• mass and weight

Your mass increases on a large planet with more gravity.

• True
• False

On Earth, which has a greater gravitational force acting on it?

• an iPhone

• a laptop

• a dog

• a car

Gravity on the moon is about 1/6 the gravity felt on the earth. This is because

• the moon is much less massive than the earth
• the earth has a molten core and the moon doesn't
• the moon is so much further from the sun than the earth.
• the moon is so far away from the earth
