Lecture 05 — Potential energy and energy conservation
Learning objectives
Students should be able to:
- Calculate gravitational and elastic potential energy, and say when a force has a potential energy.
- Apply conservation of mechanical energy to find speeds and heights.
- Include friction and other forces in an energy equation, and say where the energy goes.
- Find a force from a potential energy, and read an energy diagram.
