iGCSE Physics PowerPoint that covers the topic of Work Done. This 14 page powerpoint explains how frictional forces, including air resistance, needs to be overcome to keep an object moving. This is investigated with two practicals (one looking at surfaces and the second similar / extension practical looking at the effect of changing the weight of the object on friction). Graphing skills with extrapolation are also highlighted.
This is the fourth of 6 topics in this units of work and is aimed at covering approximately 2-3 hours of teaching, including the experiments.
