Principles
Conservation of Energy
Conservation of Momentum The momentum p of a particle is the product of its mass
and its velocity: p = mv. (a vector.)
Total momentum before collision = Total momentum after collision

Principles
Diagram 1 is a representation of the set-up we will use. We place the ball at a fixed
position on the ramp (the dynamics track) and release it from rest. As the ball rolls
down the ramp, its initi
Energy in Atwoods Machine
Chenbo sun
Principles
The mechanical energy of a system is the sum of its kinetic (K) and
potential energies (U):
E=K+U
Kinetic Energy is energy that an object has by virtue of its mass m
and its speed v. It is defined as:
K=1/2m

Weight and mass
The forces in these experiments will be the weights of various masses. The
weight W of any mass m is given by:W = mg (g = 9.80 m/s2)
Ax = Acos and Ay = Asin
A = Ax2 + Ay2

Principles
Translational and Rotational Equilibrium
In order for a particle to be in static equilibrium (i.e., stationary over time), the sum of
the forces on it must be zero:
F = 0
