13 momentum – the product of an object’s mass and velocity momentum = mass x velocity
14 What is the momentum of a bird with a mass of 0.018kg flying at 15m/s?
15 A golf ball travels at 16m/s, while a baseball moves at 7m/s A golf ball travels at 16m/s, while a baseball moves at 7m/s. The mass of the golf ball is 0.045kg and the mass of the baseball is 0.14kg. Which has the greater momentum?
16 Law of Conservation of Momentum – in the absence of outside forces, the total momentum of objects that interact does not change.
