Sliding friction happens when something is rolling.

True or False

Friction is the force that

• creates gravity.

• does nothing to movement.

• makes things slide fast.

• opposes movement.

Static Friction happens between

• a balloon and my hair.

• surfaces not in motion.

• two smooth objects.

• all things.

When an object rolls freely over a surface, it is called,

• Rolling Friction

• Sliding Friction

• Static Friction

• Fluid Friction

This force keeps the planets from flying off into space.
