Question

What kinds of friction do you know and explain with suitable example.​

Answer 1

Kinetic friction :

Kinetic friction is defined as a force that acts between moving surfaces. A body moving on the surface experiences a force in the opposite direction of its movement. The magnitude of the force will depend on the coefficient of kinetic friction between the two materials.

Exampes:

Movement of a snake.

Moving on roller skates.

Mountain Skiing.

Answer 2

Answer:

1) Static friction - when you apply force and the object does not move. 2) Sliding friction - when the surface if the object moves on other. 3) Rolling friction - when any wheel or ball moves on any surface rolling friction is applied. it is very less than sliding friction.
