Impulse: something that changes the momentum of an object.  Force•time=mass•change in momentum

Work: when a force moves an object (causes displacement).  Work= force•distance

From the equations above, it can be mathematically calculated that:

distance (mass•change in momentum)=work•time

The relationship between these two objects is that in order for an object to have a change in momentum, it must have work done to it.


The force exerted on the cart is equal to the mass• acceleration.
