7. On a distance-time graph what does the gradient show?

  • The position of an object
  • The rate of change of distance
  • The rate of change of velocity
  • The rate of change of time

8. What instrument is used to measure forces?

  • trigonometer

  • newtonmeter
  • pedometer

9. what is acceleration measured in

  • ms-1
  • ms-2
  • ms2
  • mps

10. What is the formula for efficiency

  • efficiency=useful energy produced/total energy supplied
  • efficiency=useful energy supplied/total energy produced
  • efficiency= total energy supplied/ useful energy produced
  • efficiency= total energy produced/useful energy supplied

11. In a sankey diagram which way does useful energy go

  • above
  • below
  • straight on
  • off the side

12. What is power

  • The government
  • The rate of speed
  • The rate of changing energy
  • A sense of status

13. give the formula for waste energy

  • waste energy=total energy supplied-useful energy produced
  • waste energy=total energy produced-useful energy supplied
  • waste energy=useful energy produced-total energy supplied
  • waste energy=useful energy supplied- total energy produced

14. Give the formula for weight

  • weight= gravity-mass
  • weight= mass/gravity
  • weight=mass x gravity
  • weight= gravity/mass

15. Name six types of energy

  • light, heat, sound, solar, electrical, kinetic

  • light, elastic, gravitational, chemical, speed, heat
  • light, sound, sight, touch, taste, telepathy

16. What is weight?

  • A force called gravity
  • An object's mass
  • The pull of gravity of a planet on an object's mass
  • Something we put on

17. What is constant and never changes

  • gravity
  • newtons
  • mass
  • weight

18. What is the formula for acceleration

  • acceleration=time/velocity
  • acceleration=time taken/change in velocity
  • acceleration=change in velocity/time taken
  • acceleration=velocity/time

19. If we cancel out forces in opposite directions what is left over

  • nothing
  • The resultant force
  • resistance
  • acceleration

20. What is the formula to find velocity

  • velocity=distance x time
  • velocity=distance/time
  • velocity=time/distance
  • velocity=distance-time
