Question

what is friction ?what is fluid friction? what is rolling 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: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

Answer 2

Answer:

#1 Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

#2 Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other.

#3 Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body rolls on a surface.
