Question

Why and how Does friction produce heat??

Answer 1

$\huge\mathfrak\pink{Answer!}$

Friction is a force that opposes motion between any surfaces that are touching. Friction occurs because no surface is perfectly smooth. ... Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.

Answer 2

Answer:

Explanation:

You know that friction produces heat. That's why rubbing your hands together makes them warmer. But do you know why? Friction causes the molecules on rubbing surfaces to move faster, so they have more energy. This gives them a higher temperature, and they feel warmer. Heat from friction can be useful. It not only warms your hands. It also lets you light a match as shown in the Figure below. On the other hand, heat from friction between moving parts inside a car engine can be a big problem. It can cause the car to overheat.
