Chapter 7 Motion
... • A powerful locomotive begins to pull a long line of boxcars that were sitting at rest. Since the boxcars are so massive, they have a great deal of inertia and it takes a large force to change their motion. Once they are moving, it takes a large force to stop them. • On your way to school, a bug fl ...

... By measuring a and T one can use this relation to determine the mass M. It is in this way that we determine relatively easily the mass of the sun and the masses of those planets (such as earth) having moons. Actually, if we had taken into account the neglected motion of M around the CM of the syste ...

Circular Motion
... Uniform Circular Motion, UCM: moving in a circle with a constant speed. Question: Is there a constant velocity when an object moves in a circle with a constant speed? No, the direction changes, therefore the velocity changes. If the velocity changed, the object is actually ACCELERATING even while m ...
