Friction and Force
friction is a type of force that opposes the motion of the object. Suppose an object moving on the floor comes to rest eventually, this is because of the friction. Generally when an object moves friction and force working on that body are opposite to each other. Suppose a force (f) works on the body then the friction force working on the body is,
Friction Force (F) = -μf
where,
- – sign indicates that friction force is opposite to the motion of the object
- μ is Coefficient of friction

Friction
Friction in Physics is defined as a type of force that always opposes the motion of the object on which it is applied. Suppose we kick a football and it rolls for some distance and eventually it stops after rolling for some time. This is because of the friction force between the ball and the ground. Here, the force acting opposite to the motion of the ball that stops the ball is called the friction or friction force. Friction acts between two surfaces when one surface is in a state of motion.
In this article, we will learn about, Friction, Factors Affecting Friction, Causes of Friction, its advantages, disadvantages, and others in detail.
