Question

what type of frictions
​

Answer 1

Answer:

There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases.

Answer 2

1) Static friction- The friction that exists between the two surfaces in contact when there is relative motion between them is about to start is called static friction.

2) Kinetic friction-The friction that exists between a surface sliding on another surface is called kinetic friction.

3) Rolling friction-When a body rolls on the the surface of another, the friction that exists between the surfaces is called static friction.
