Question

GIVE DIFINE OF FRICTION

Answer 1

Explanation:

⚫Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other.

⚫It is also called as kinetic friction. It is that force that keeps a surface sliding with another surface. For example, if book is kept on floor and the book moves with respect to the floor. It is the frictional force between two surfaces that are rubbing against each other.

Answer 2

• Ans=Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
