Question

Define force of friction​

Answer 1

Answer:

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other

Friction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down. The amount of friction depends on the materials from which the two surfaces are made. The rougher the surface, the more friction is produced. Friction also produces heat.

Answer 2

Frictional force refers to the force generated by two surfaces that contacts and slides against each other .
