Proving Hooke's law
Aim
My aim for this experiment is to verify Hooke's law, which is F = MX.
Prediction
I predict that the length will increase in relationship with the increase in mass.
F = MX
M = 1.5
X (cm) 2 4 6 8 10
F (n) 3 6 9 12 15
See prediction graph.
Method
The apparatus was set up as shown. We measured the length of the spring, using a ruler, every time we added mass to it and recorded the results.
Safety
Normal laboratory safety conditions apply. We wore goggles throughout this experiment to protect our eyes from snapping elastic bands.
Results
Spring
We measured the spring before we started to add mass and it was 4.7cm in length.
I calculated what 'm' would be for each result.
