Question
The work done by a body against friction always results in(a) loss of kinetic energy(b) loss of potential energy(c) gain of kinetic energy(d) gain of potential energy
Step 1
So, if a body does work against friction, its kinetic energy will decrease. This is based on the work-energy theorem which states that the work done on an object is equal to the change in its kinetic energy. Show more…
