My question is CHANGE IN KE .
For example when a block is slowly descending down an incline with friction, in that case the change in KE=0. It means that we have to consider the work done by friction also. Becoz if we consider the work done by mg only, than it would tend to increase the KE of the body. But as change in KE=0, it means that the work done by friction will aslo be considered.
The quality of a person's life is in direct proportion to their commitment to excellence, regardless of their chosen field of endeavor.

It is during our darkest moments that we must focus to see the light.
