I want to have the intuition of the mass times velocity. I know that it's equal to the momentum, but it doesn't make any sense to me to multiply the mass of a body times it's velocity. I think it's meaningless. it's just like multiplying the volume of a body times it's acceleration !!! I'll be grateful to anyone who can give the intuition of it.
If you have a bicycle rider of mass m1 moving at 15m/s towards a cement truck of mass m2 going -15m/s in the opposite direction, the greater momentum determines the outcome of the collision (besides the untimely end of the cyclist). What ends up where? Prof Walter Lewin at MIT gives a great lecture and demonstration here: http://www.youtube.com/watch?v=0DR8emfSsF0&feature=bf_prev&list=ECF688ECB2FF119649
thanks , I'll watch it and i hope it'll be useful :)
