  1. Power = 
    • work done
    • Time interval 
  2. Mechanical energy 
    the energy due to the position of something or the movement of something
  3. potential energy
    the energy that is stored and held in reading it
  4. gravitational potential energy = 
    weight X height ( PE = mgh) 
  5. kinetic energy = 
    1/2 mass X speed squared 
  6. kinetic energy
    depends on the mass of the object as well as its speed
  7. Net force X distance = 
    kinetic energy
  8. Work = 
    Change (KE) 
  9. work-energy theorem
    work equip change in kinetic energy
  10. work
    the effort exerted on something that will change its energy
  11. work = 
    force X distance
  12. conservation of energy
    energy cannot be created or destroyed it may be transformed from 1 form into another but the total amount of energy never changes
  13. Efficiency =  
    • useful energy output 
    • Total energy input
