## Systems Of Particles

Systems Of Particles Shows two particles of masses ml and m separated by a distance d. We have arbitrarily chosen the origin of the .r axis to coincide with the particle of mass mi’ We define the position of the center of mass (com) of this two-particle system to be. The three scalar equations of can now be …

## The Center of Mass

The Center of Mass We shall now spend some time determining how to find the center of mass in various systems. We start with a system of a few particles, and then we consider a system of a great many particles (as in a baseball bat).

## A special Point

A special Point Physicists love to look at something complicated and find in it something simple and familiar. Here is an example. If you flip a baseball bat into the air, its motion as it turns is clearly more complicated than that of, say, a non spinning tossed ball , which moves like a particle. The center of …

Systems of Particles If you leap forward chances are that your head and torso will follow a parabolic path, like a baseball-thrown in from the outfield. However,when.a skilled ballet dancer leaps across the stage in a grance the path taken by her head and tor so is nearly horizontal of the jump. She seems to be flowering …
