Answer:
Friction
Friction is a force that holds back the movement of a sliding object.
Friction can be useful.
For example: friction between our shoes and the floor stop us from slipping. friction between tyres and the road stop cars from skidding.
Friction can also cause problems in a car. Friction between moving engine parts increases their temperature and causes the parts to wear down.
