Question

difine frictional force and sliding friction
​

Answer 1

Answer:

The term sliding friction refers to the resistance created by two objects sliding against each other. This can also be called kinetic friction. Sliding friction is intended to stop an object from moving.

Friction is the force that resists motion when the surface of one object comes in contact with the surface of another

Answer 2

Frictional force:-

Force between two surfaces in contact ; it usually

acts opposite to the direction of motion .

Sliding friction :-

The friction that acts between an object and a surface when the object is sliding over that surface .
