Force and extension of the spring (Required Practical)

Question 1

what are the equipment that you are going to need to work out the force and extension of a spring

Answer 1

a clamp stand, two bosses and two clamps.

Question 2

What are the steps to figure out the extension and the force of a spring

Answer 2

1.We now place a heavy weight on the clamp stand to stop it falling over.

2. Next we attach a meter rule and a spring
3. The top of the spring must be at the zero point on the meter rule.
4. It is really important that the meter rule is vertical otherwise the readings will be inaccurate.
5. The bottom of the spring has a wooden splint attached as a pointer.
6. This pointer must be horizontal or the readings will be inaccurate.
7. We now read the position of this pointer on the metre rule.
8. This is the unstretched length of the spring (the length with no force attached).
9. Next we hang a 1 N weight on the spring.
10. We now read the new position of the pointer on the metre rule.
11. We continue adding 1 N weights to the spring and reading the position of the pointer.
12. This shows you a close-up of the meter rule.
13. We now need to work out the extension produced by adding each weight.
14. To do that, we subtract the length of the unstretched spring from each reading.

Question 3

how do you work out the weight of the object using the graph

Answer 3

1. To do that, we need to measure extension of the spring when the stone is hanging from it.
2. We then read the weight of the stone from the graph. going down

Question 4

what do you call a spring that has broken and doesn’t come back to into normal form

Answer 4

it has been pushed its limit of proportionality

Question 5

what is the formula to work out the spring constant

Answer 5

dividing the force by the extension
