What is frictional force?

Frictional Force refers to the force generated by two surfaces that contacts and slides against each other. These forces are mainly affected by the surface texture and amount of force impelling them together. The angle and position of the object affect the amount of frictional force.

Force that opposes a motion of a body in opposite direction

Friction is a force that is created whenever two surfaces move or try to move across each other. Friction always opposes the motion or attempted motion of one surface across another surface. Friction is dependant on the texture of both surfaces.

To stop a moving object, a force must act in the direction opposite to that of the motion. Friction is a force that opposes the motion of an object. There are different types of friction, such as static, fluid and rolling friction

Explanation:

force that comes in contact with another object
