6. What do you do after each mass is added?

  • Nothing
  • Measure the length of the spring.
  • Add more masses

7. How do you know if the spring has obeyed Hooke’s law?

  • The line of best fit will be straight.
  • The graph will curve
  • The graph will be straight then curve
  • No line of best fit

8. What could happen if you don’t wear safety goggles?

  • If the spring snaps, you could injure ur eyes
  • Nothing
  • You could get hurt

9. What is the third step in this practical?

  • Measure spring
  • After each mass, measure the length of the spring.
  • Add more mass
  • Nothing

10. Why should you use a pointer?

  • To help measure the length of the spring.
  • To measure
  • I dont know
  • Nothing

11. What should the gradient equal if it obeys Hooke’s law?

  • Extension
  • Gradient= spring constant
  • Line of best fit
  • Spring length

12. What should be on the x and y axis

  • Force against extension
  • Weight and spring
  • Length and weight

13. What should happen to you graph if you load enough masses?

  • It will obey Hooke’s law
  • The graph should start to curve
  • The graph should be straight

14. What is the equation for extension?

  • Extension= new length- original length
  • Extension= original length-new length

15. Why must you stand up when doing this practical?

  • So you can move from falling weight
  • To be safer
