Brief description


Classical Physics describes the macroscopic world of electricity, magnetism, mechanics, optics, heat and sound, the knowledge of which underpins much of today's engineering and technology. The origins of classical physics, though, lie in the microscopic world of electrons, atoms and molecules and many phenomena at this level can be inferred at least qualitatively from classical ideas. Concepts like electric charge and current, electric and magnetic fields and electromagnetic induction describe the operation both of electric circuits and of dielectric and magnetic materials. Together with the ideas of mass, displacement, restoring force and friction, potential and kinetic energy, they furnish our understanding of oscillatory and wave motion and form the basis for defining temperature, heat transfer and also the propagation of sound and light. This module concentrates on electricity, magnetism, current electricity, oscillations, heat and temperature, waves, sound and light.
