Graphing on log-log Paper
Suppose you were presented with the set of data shown below. A graph of x vs. t is also shown, and you
can see it's a smooth curve. But other than that, it's not very informative. Suppose, howeve

Systems of Particles
Center of Mass (CM) :
We wish to show that a body or system of
particles move as if
1. all of its mass were concentrated at one
geometric point in space called the CM, and
2. the net external Force was applied there.

Ch 8: Moron
When a conservative force does work on an
object w/in a system, that force transfers
Energy between the Kinetic Energy of the object
and the Potential Energy of the system.
Consider a system of objects:

Drop the bal
Work and Energy
Force: any agent of change.
Recall from Ch4:
~ , is the capacity a body or system
has to cause change.
Work is Energy transferred to (+) or
removed from (-) a system or body by means
of a force acting on it.
Work and Energy are s
