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
