Question

Give examples of how is friction responsible for energy wastages?

Answer 1

power energy wasted when a vehicle running is stopped by a break.

Answer 2

According to the friction concept,
                                                       (1)when a Tyre deflates it is difficult to move the vehicle because of increased friction between the Tyre & road.

the friction.
