Quiz on Gravitational Forces

What does gravitational force depend on between objects?

• Color and shape

• Mass and energy

• Temperature and speed

• Texture and size

How does the size (mass) of an object affect the force of gravity?

• The smaller the object, the stronger the force

• The bigger the object, the stronger the force

• Size does not affect gravity

• The bigger the object, the weaker the force

What is the main difference between mass and weight?

• Mass changes with location, weight does not.

• Mass is the amount of force, weight is the amount of matter.
