CHAPTER 1 Forces in action
... When explaining changes in motion, it is necessary to consider another property of the object — its mass. It is clear that it is more difficult, for example, to stop a truck moving at 20 m s−1 than it is to stop a tennis ball moving at the same speed. The physical quantity momentum is useful in expl ...
