Is the increase in kinetic energy equal to the decrease in potential energy?

Is the increase in kinetic energy equal to the decrease in potential energy?

Any response would be greatly appreciated!
Thanks in advance!

Not always in classical mechanics. (I've no idea in relativity).
For instance a man starting from rest who begin to run on a plane ground. His kinetic energy will increase while his potential energy will remain constant.

But if you're dealing with a mass attached to a spring, of a falling object then the answer to your question is yes.
