Physics will involve the use of the metric system in problem solving. The application of mathematics such as geometry, algebra and trigonometry will be shown through problem solving. Physics has three main divisions including mechanics, electricity and wave properties (light & sound). Mechanics covers Newton's Laws and the principles of thermodynamics. Electricity involves the understanding of the subatomic particles and the use of electrons in showing static charge, circuits and currents. Wave properties include the properties of refraction , reflection, diffraction and interference. The use of the lens equations will also be applied.
