Answer 2

$\huge\bold\green{Hyy!}$

● Frictional force refers to the force generated by two surfaces that contacts and slide against each other. ... If an object is pushed against the surface, then the frictional force will be increased and becomes more than the weight of the object.

EXAMPLES:-

1) Rubbing both hands together to create heat.

2) a person sliding down a slide is an example of sliding friction.
