Specification

understand the difference between the gravitational and kinetic energy
gravitational potential energy = mass * gravity * height
kinetic energy = 1/2 mv2
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 = ½ mv2
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
