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

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

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

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

8. What is the first step in this practical?

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

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

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

10. How would you make sure this experiment is carried out safely?

  • By Standing up and wearing safety goggles
  • Sitting down
  • Wearing gloves

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

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

12. What is the second step in this practical?

  • Increase the force
  • Weigh your masses and add them one at a time
  • Add your masses

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

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

14. 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
