Lecture 16 - Circular Motion
... Newton knew that at the surface of the earth bodies (apples) fall 5 m in the first second, and that this acceleration is due to earth’s gravity. He showed that the gravity force is the same as if all earth’s mass were at its center, 4000 mi from the surface. (This required inventing Calculus). He wo ...

The more momentum an object has, the more difficult it is to stop
... When stopping an object, the impulse will be the change in momentum and therefore will be the same number regardless of the time involved. However, the force can change drastically depending upon the amount of time in which the object is brought to a halt. As the length of time is increased, the for ...
