|Friction is caused by two forces rubbing together. When it is rough the friction will be more than if it is smooth. Friction will slow or stop an object from moving. Brakes cause pressure on the wheel causing friction which will slow a car or bike down. Sliding is easier on a smooth floor than on a rough carpet.
