What effect does friction have on a moving object?

• Friction causes the moving object to slow and eventually stop.

• Friction causes the moving object to speed up.

• Friction keeps the moving object moving in the same direction forever.

• Friction causes the moving object to turn around and move in the opposite direction.

This motion graph represents:

• an object at a constant speed

• an object accelerating

• an object at rest

• an object on flat ground

2. ______________________ is a push or pull on an object.
