Momentum

Abstract

This programme begins with a summary of what has already been covered in Programme 1 on Momentum and we shall examine some problems which need a little more ingenuity to solve. We shall introduce and define the Coefficient of Restitution. Then Angular Momentum will be defined and discussed, and the results of ‘collision’ of two rotating systems, or one rotating and one translating system. This will require a close investigation into the principle of Conservation of Angular Momentum, and an explanation will be required for this principle apparently failing to apply to certain situations. We shall look at some examples which emphasise the vector aspect of momentum, and finally, we shall examine the effect of an impulsive blow on a single body which rotates, or which simultaneously rotates and translates.
