Physics Powerpoint presentations A level deriving Circular Motion and SimpleHarmonic Motion eqns.

Intended for A level Physics Teachers
These two presentations give a holistic ( physical ) view of how to think of the derivation of the equations for :-
a) Circular motion …relating them to a natural view of angle
b) Simple Harmonic motion : showing how the equations are intimately related to circular motion
The objective is to give students tools to give meaning and access these equations for themselves rather than simply learning them by rote or learning purely mathematical derivations
