Circular Motion
... For the problems from this chapter, you need to recall the definitions of frequency, period, and know how to use the fact that that an object moving in a circle with constant speed has speed given by v = 2πr / T. Note that this is not on your OSE sheet. Perhaps it should be. circumference = 2πr spee ...

P1_Forces on a System of Objects
... A system of objects has a special location which is called the system’s center of mass (CM). A single object also has a center of mass, because a single object is actually a system of objects called “atoms”. If the system consists only of two objects, then the CM is on the line joining the two objec ...

Speed & Velocity

Chapter 7: Momentum
... An impulse produces a change in momentum. If the force is not constant but varies with time, we find impulse is the area under the curve of a F vs t graph. If the impulse is zero, there is no change of momentum -- it is conserved. Example: A rubber ball mass 0.100kg moving east at 10.0 m/s hits a wa ...
