Personal power measurement practical

GCSE practical. Orginally designed to compare the power of bicep curls compared with step ups via calculation of the gain in gravitational potential energy (both sheets included). I have done this with a range of lift variations sometimes as a whole class practical or sometimes just measure one volunteer as an example (can be compared with teachers power). I have also included a variation where the calculation is completed via work done, as some courses leave GPE calculations until later.
