Work and Power

• • Work done is the useful energy transferred . It is measured in Joules.
• • Two main types of work can be done: work done against a force and work done through heating. The work done against a force is given by the equation…
  • Work done = Force * Distance moved
  • (J). (N). (Metres)
• When a force moves an object , energy is transferred and work is done.
• The Law of conservation of energy

  • Energy cannot be created or destroyed , it can only be transferred into different forms
• The tens forms of energy are :

  1. Magnetic
  2. Kinetic
  3. Heat
  4. Light
  5. Gravitational potential
  6. Chemical
  7. Sound
  8. Electrical
  9. Elastic
  10. Nuclear
