A set of five springs all with the same length but with different spring constants for verification of Hooke's Law.

Each spring has an eye at one end and a hook at the other, with a built in pointer to accurately record the results of your experiments.

The springs stretch 2 cm with a load of 0.5N, 1N, 2N, 3N and 5N respectively. Springs come with a built in ring to hang, with a hook to carry weights and a red indicator.

Spring constants are: 0.5, 1, 2, 3 and 5 N/m.
