Contents
Specification
- understand the difference between the gravitational and kinetic energy
- gravitational potential energy = mass * gravity * height
- kinetic energy = 1/2 * mass * velocity
- understand how conservation of energy produces a link between GPE, Ke and work done
Main Body of Lesson
- Unserstand that kinetic energy is energy of motion
