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.

X (cm) 0 0.5 0.8 1.3 1.8 2.3 2.8 4.8 6.6

Elastic band

We measured the elastic band before we started to add mass and it was 8.5cm long.

I calculated what 'm' would be for each result.
