We have covered the theory of work done so now it’s time to look at some simple machines that trade force against distance to make tasks easier than they would otherwise be. In this post we will look at levers and gears, which "magnify" forces by moving a smaller force through a larger distance. This … Continue reading Levers and Gears

The basics of energy stores and transfers are covered in a separate post (click here to refresh your memory if necessary). We now need to think specifically about ways in which energy can be transferred by the action of forces. For the purposes of GCSE Physics, we will restrict our thoughts to mechanical forces but … Continue reading Work Done and GPE
