GCSE physics practicals

Change one quantity, measure another, then use an equation and a graph.

The kinds of experiment

Heating a block to find how much energy it takes to warm it, measuring how resistance changes with the length of a wire, finding the density of solids and liquids, stretching a spring, measuring how acceleration changes with force, timing waves, and tracing light through glass blocks.

Try them in a simulation first

A simulation is not a substitute for the real experiment, but it shows what changes when you change one thing.

Questions

Why do practical questions ask for a graph?

A straight-line graph shows how two quantities are linked, and its gradient often gives the answer, for example a spring constant.
