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
- Kinetic energy = 1/2 mv
- understand that gravitational potential energy is the energy due the position of an object
- GPE = mgh
- understand and use Work Done = Energy transferred!
- recall efficiency
- use 'efficiency of a ramp' work sheet ( Science Shared)for the practical aspect of this lesson
