AP Physics 1 and AP Physics C: Mech (Part 17: Potential Energy) | Office Hours with Al

In this stream we introduced the concept of potential energy, followed by a discussion of conservative forces and conservation of mechanical energy. We also looked at the energy associated with springs. The rest of our time was spent working on book problems and discussing the insights they could give us.
