6. What is power?

  • Rate at which work is done
  • Force exerted over a distance

7. What happens when to pressure when you have a smaller area?

  • No pressure
  • More pressure
  • Less pressure

8. What is the center of mass?

  • The point at which all plumb lines meet
  • The center of an object

9. How can you increase power?

  • Doing something faster(taking less time to do) and using more strength to push something
  • Moving something up and down

10. What is force measured in?

  • MM
  • Newtons
  • KG

11. How can you get a resultant force?

  • By multiplying the forces
  • By finding the difference between forces
  • By adding up the forces

12. What is tension?

  • Stretching force
  • Squeezing/squashing force

13. What is the relationship between Hooke's Law?

  • Force and the stretch of a spring
  • Force and weight of a string
  • Weight and stretch of a string

14. When does the object stay stationary or have a constant speed?

  • When all the forces add up to an odd number
  • When all the forces cancel out
  • When all the forces add up to an even number

15. What is a moment force?

  • The turning effect
  • The moment something happens
  • The time at which the force changes

16. What happens to pressure when you have a larger area?

  • No pressure
  • Less pressure
  • More pressure

17. When is there a greater turning effect?

  • Further from the pivot point and greater force applied
  • Closer to the pivot point and less force applied

18. When is there less of a turning effect?

  • Closer to the pivot point and less force applied
  • Further from the pivot point and greater force applied

19. What does a manometer measure?

  • Measures the atmospheric pressure (height of the mercury inside the glass)
  • The difference between atmospheric pressure and gas pressure
  • The difference between atmospheric pressure and liquid
