[Oliviam12]

Homework Statement

True/False If there is no motion in a system, no work can be done.

Homework Equations

W=$$\Delta$$K

The Attempt at a Solution

I think the answer is False, because of potential energy but, I am not 100% sure... Any sites on the topic are welcome seeing as my book still hasn't come in...

Have a look at how work is defined and then read the question. Here is a useful site with information on work, energy and power.
