What is friction?

Back

A force that opposes the motion of an object, caused by the contact between two surfaces.

Front

How does mass affect motion?

Back

The greater the mass of an object, the more force is needed to change its motion.

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is inertia?
