This PowerPoint goes through the mathematics needed to calculate Kinetic, Work Done and Gravitational Potential Energy. It builds on and reviews velocity calculations. There are two versions of a step-by-step object on a slope experiment which will enable pupils to test the equating of the formulae for Kinetic energy and Work Done and utilise this for calculating braking forces due to friction.

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.

This PowerPoint lesson on Generators shows how a rotating coil within a magnetic field can produce a sinusoidal output voltage (potential difference) in a circuit. Oscilloscope readings for an AC suply are looked at in detail so that students can calculate the peak voltage and time period from a diagram. Output wave forms are considered and examples are shown on how these change when the variables of the rotating coil are changed. Finally the engineering systems in a power station generator are covered. This is the seventh (of 8) lessons in this section entitled “Magnetism and Electromagnetism” which is available as a bundle in our shop.

This PowerPoint lesson on Electromagnetic Induction covers the Right-hand Rule for working out the current flow direction for a wire which is moved within a magnetic field, the application of this in creating an output voltage (Potential difference) in a coil and the creation of a sine wave from a rotating magnet in a sensor circuit (e.g. for fluid flow) This is the sixth (of 8) lessons in this section entitled “Magnetism and Electromagnetism” which is available as a bundle in our shop.
