Momentum
... Impulse and Momentum • If momentum changes, it’s because mass or velocity change. • Most often mass doesn’t change so velocity changes and that is acceleration. • And mass x acceleration = force • Applying a force over a time interval to an object changes the momentum • Force x time interval = Impu ...

... mom. of truck before + mom. of car before = mom of (car+truck) after i.e. mt vt - mc vc = (mt+mc) v (- on left because opp dir) (15000)(30) - (1000)(60) = (16000) v So, v = 24.375 km/h Note that they do eventually come to rest because of friction on the road – an external force. Since the impact tim ...

4.1 Momentum and Impulse
... The work that is done is the amount of energy that is transferred to the object. The force and displacement must be in the same dimension. Work is a scalar quantity measured in Joules (J). A 1 N force acting through 1 m does 1 J of work. Work is calculated with constant or average forces. For our pu ...
