External Energy Transfer

The External Energy Transfer Video Tutorial conceptually and quantitatively describes the changes that occur in the system's energy when net work is done on it by a non-conservative force. Numerous example problems are given and solved.

The video lesson answers the following questions:

How do you analyze situations in which work is done on a system by an external force?
