Question

what is friction and tell types of friction​

Answer 1

Explanation:

Friction is the force that opposes motion between any surfaces that are in contact. 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

Answer 2

Dry friction resists the relative lateral motion of two solid surfaces in contact. Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. ... Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body.
