Electric Potential Difference: Students learn to describe changes in the potential and kinetic energy of a point charge as it moves in an electrical field. Potential difference is introduced in ...

(Mass Appeal) – Do you know the difference between potential and kinetic energy? I certainly don’t, which is why Dr. T, a Science Educator from the Springfield Museums, is with us today.

The Work Energy Principle is one of the big ideas in introductory physics courses. It's so big that the textbook presentation can get a little confusing - but it doesn't have to be that way.
