Impulse can be presented in two different ways. Meanwhile a short collision or impact time causes a large. Because of the impulse-momentum theorem we can make a direct connection between how a force acts on an object over time and the motion of the object.
Below we derive impulse from the equation F ma which comes from Newtons second law of motion.
Impulse is the change of momentum of an object when the object is acted upon by a force for an interval of time. Is a vector quantity since velocity is a vector and mass is a scalar. Thus I the impulse is equal to a force F x time t. The impulse equals the momentum change.
