This week in physics we learned about Linear Momentum on one axis. The si unit for momentum is kg x m/s. This is because mass times velocity is equal to momentum. Momentum in is equal to momentum out which means that everything must start and end with the same momentum. So a heavy person running slow will probably have the same momentum as a lighter person running faster than him. This is why in football, if your small, you should run as fast as you can into them. In this picture Kory has more momentum than the guy on the ground because even though their mass is the same, Kory has more velocity which means he has more momentum.
