Across
- 1. increase this to increase g.p.e.
- 5. unit of force
- 7. gpe in kJ gained when a mass of 20kg moved up by 10m
- 8. force times this equals work done
- 10. work in J when 5N moves by 4m
- 12. power equals energy transfer ******* by time
- 13. distance in cm when 4N does 2J of work
- 15. measured in newtons
- 16. unit of power
- 17. unit of work
- 19. you need this to do work
- 21. how quickly work is done
- 22. work equals force ********** by displacement
Down
- 2. type of potential energy gained when a weight is lifted
- 3. when working out k.e. speed is ?
- 4. the less of this the more powerful a machine is
- 6. moving
- 7. power in kW when 60kJ of work done in 20s
- 9. energy that can be released
- 11. ke in J of mass of 2kg travelling at 4m/s
- 14. when this moves work is done
- 16. energy is needed to do this
- 18. the more of this the greater is the k.e.
- 20. speed in m/s of body mass 4kg having ke of 32J
