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. ...

... Example Problem Show that when a constant net force F is applied to an object of mass m for a time Dt, its change in velocity is FDt Dv = m Strategy: We can find acceleration using Newton’s second law a = F/m. Then we can find Dv using the definition of acceleration a = Dv/Dt. ...
