OUTCOME
By the end of the lesson you will identify the concept of impulse and recognise its connection to momentum and force and be able to use Force time graph to find impulse.
Momentum is the velocity time the mass. The force on an object is related to the momentum through a value called the impulse.
I = Ft = change in momentum
