$\mathfrak\pink{what \: \: is \: \: \: \: friction \: }$
??

Answer 1

Answer:

Friction is a force that opposes motion between any surfaces that are touching. Friction can work for or against us. For example, putting sand on an icy sidewalk increases friction so you are less likely to slip. On the other hand, too much friction between moving parts in a car engine can cause the parts to wear out.

Answer 2

Answer:

Friction is a force between two surfaces that are sliding, or trying to slide, across each other. ... Friction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down.
