Momentum and Impulse notes
... What does momentum and impulse have to do with each other? Momentum = mv If velocity changes, momentum changes, and acceleration (either + or –) occurs But we know: 1. for acceleration to occur, a force has to be applied. 2. If a given force is applied over a longer time, more acceleration occurs. ...
