Lesson Order
- 4-ENG-01 Work done. Power.
- 4-ENG-02 Kinetic and potential energy. Conservation of energy.
- 4-ENG-03 Energy Circus
- 4-ENG-04 Revision and test
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
