Question

What is the definition of frictionnal force?

Answer 1

Friction is a force that holds back the movement of a sliding object. That's it. Friction is just that simple. You will find friction everywhere that objects come into contact with each other. The force acts in the opposite direction to the way an object wants to slide.

Answer 2

Frictional Force refers to the force generated by two surfaces that contacts and slide 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.
