Answer 2

$\huge{ \mathfrak{answer}}$

Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force.

Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.

$\red{Friction \: \: produces \: \: heat \: \: because \: \: it \: \: causes \: \: the \: \: }$

$\red{molecules \: \: on \: \: rubbing \: \: surfaces \: \: }$

$\red{to \: \: move \: \: faster \: \: and \: \: have \: \: more \: \: energy.}$
