Question

Work done against friction definition

Answer 1

Explanation:

For example, when a bike applies its brakes and slows down the kinetic energy of the bike is transformed into heat energy in the brakes. How much energy is lost depends on the frictional force ( ) and the distance over which the frictional force is acting ( This is called the Work Done against Friction)

Answer 2

Answer:

irreversible process

Explanation:

The presence of friction always results in the absolute value of the work output of a system undergoing a direct process being smaller than the work transferred into the system from the outside during the reverse process
