Hooke’s Law Graphs

✏️ Paper first! Work out every question on paper before you open the answer. Write down every step – the equation, the numbers with units, the rearranging and the answer with its unit. In the exam, if your final answer is wrong you can still get marks for correct working, but only if the examiner can see it.

Find spring constants, forces and elastic potential energy from force–extension graphs. A new spring every time, with the gradient or reading drawn on in the worked solution.

Worked solution

    F = k × e, with extension e in metres. The spring constant k is the gradient of the straight part of a force–extension graph. Elastic potential energy E = ½ k e² (given on the equation sheet).
