Question

what are the type of friction.

Answer 1

sliding friction 
static friction 
kinetic friction

Answer 2

There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases.
There are two main types of friction, staticfriction and kinetic friction. Static frictionoperates between two surfaces that aren't moving relative to each other, while kineticfriction acts between objects in motion
