Across
  1. 3. the force that commonly causes an energy transfer to not be 100% efficient
  2. 5. this is needed to make stationary objects move, to change an objects shape or warm them
  3. 6. the rate of energy transfer
  4. 10. the power of an electrical component can be calculated by multiplying potential difference by this quantity
  5. 13. this is done when a force is applied, causing an object to move with some component in the direction of the force
  6. 14. the relationship between mass and kinetic energy or gravitational potential energy
  7. 15. the number of energy stores
  8. 17. energy is this type of quantity, with only magnitude
  9. 18. the ratio of useful power output to total power input
  10. 19. the energy store contained by food, fuels and batteries
Down
  1. 1. the energy stored based on an objects movement
  2. 2. the principle of conservation of energy states energy cannot be created or …..?
  3. 4. the store energy is most commonly wasted to
  4. 7. the unit of energy
  5. 8. when the speed of an object doubles, it’s kinetic energy does this
  6. 9. the power of an vehicle can be calculated by multiplying force applied by this quantity
