Topics covered

• Recall and use Weight = mass * gravity
• Weight is always acting downwards (when working with diagrams)
• recall and use work done = force * distance moved in the direction of the force
• understand that work done = energy transferred
• describe power as the rate of transfer of energy or rate of doing work
• Power = work done / time
• 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
