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
