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. I haven't ...

JONNY NELSON: Energy. There are lots of different types and lots of different ways of storing it. Chemical energy in a sparkler, elastic potential energy that fires a toy into the air, and many, many ...

Solve the classic blob jump physics problem using the Work–Energy Theorem. Follow how gravitational potential energy, kinetic energy, and energy transfer explain the launch speed and maximum height, ...
