A force that opposes motion is

• friction

• inertia

• acceleration

• momentum

What effect does friction have on a moving object?

• it causes the moving object to slow and eventually stop

• it causes the moving object to speed up

• it keeps the moving object moving in the same direction forever

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