Momentum+and+Impulse+basic+understanding

We know that impulse equals momentum multiplied by velocity P=mv. But why does force multiplied by time equal massmultiplied by velocity Ft=mv, and where does it come from. It starts out with the formula force equals mass multiplied by acceleration,and accelertion F=ma, the acceleration formula acceleration equals velocity divided by time a=v/t. when we subsitute the acceleration formula inside the force formula we receive F=m(v/t). if we rearange this formula we can get Ft=mv. The formula for impulse is impulseequals mass times velocity p=mv. from this we can now determine that impulse is also equal to force multiplied by timeP=Ft, and force multiplied by time equals mass multiplied by velocity. information from physics 30 Students Notes and Problems made by Castle Rock
