# Explain Effects of Friction on Motion

Friction has an enormous influence on the motion of an object. Friction is a kind of resistive force which slows down the motion of a body. It can be defined as the force that resists the relative motion of solid surfaces, fluids, or elements that collide or slide against each other. Though friction creates many problems in our daily lives, it plays a vital role in movement and vehicle operation. Here discuss tyre’s surface, smoothness of the road, and the role of friction for controlling motion. Its effect would cause the object in motion to slow down. If the friction is increased, more energy is needed by the object to keep its momentum hence it will slow down.

Tyre’s surface

Driving vehicles is possible because of the friction between the tyres and the road surface. The friction force between the tyres and the road depends on the condition of the tyres and the surface of the road. It also depends on the weight of the vehicle. The tyre’s rubber surface is designed with treads i.e. grooves or teeth. The tyre surface is up and down due to these grooves. If the tyre is new, these grooves are distinct; as a result, the force of friction between the tyre and the road is maximum. When the tyre becomes old, their grooves are worn out and the surface becomes flat. As a result, the frictional force between the tyre and the mad decreased mostly. Say, what inconvenience may arise due to this.
