Energy stored in a spring Preliminary investigation What is the spring constant? Planning Aim - to gain an average compression rate of the spring in the trolley in order to find the spring constant. Apparatus Clamp stand 2 clamps 2 bosses, 24 0.98N weights 2 weight holders 3 labels Pencil Sprit level Trolley Ruler (measures to nearest 5 x 10-4m) Diagram Plan - I am going to investigate the spring constant of the spring in the trolley to enable me to calculate the energy stored in the spring in the major investigation. To calculate the spring constant, I need to plot my results onto a graph and draw a line of best fit. The spring constant is equal to the gradient of this straight line. To obtain my results, the above apparatus will be collected and set up as shown above. The spirit level will be used to check that the trolley is perpendicular to the ground. The trolley needs to be perpendicular to the...
