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

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

7. What should be on the x and y axis

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

8. What is the equation for extension?

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

9. What is the first step in this practical?

  • Hang the spring from the clamp then measure the spring length.
  • Stretch the spring
  • Add weights to the spring
  • Measure the extension

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

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

11. What do you do before you add the masses?

  • Put them all on the spring
  • Weigh the masses
  • Look at them
