Potential energy and conservation of energy
THIS LECTURE IS ONE OF THE MOST IMPORTANT OF THE
SEMESTER!
Potential Energy
We have seen that when a force does work on a system the system
may acquire motion energy, i.e. kinetic energy. However, another

Rotational energy and mass
Consider a rigid body rotating about a fixed axis of rotation. The
kinetic energy is by definition,
K i mi vi2 .
But we have already noted that the speed of the ith particle may be
written in terms of the angular velocity of the
Rolling motion, angular momentum vector and cross products
Now, for the physics version of Nascar racing. The entries in this
marathon are: a particle, hoop, cylinder, and sphere. These objects
are to race down an inclined plane. Neglecting friction, mech
Rotational dynamics
The effect of a force is to produce an acceleration of the object the
force acts on.
What causes an angular acceleration? This comes about by action
of a force in causing a twisting motion of that it acts on. The

Simple Harmonic Motion
THEORY
Vibration is the motion of an object back and forth over the same ground.
The most important example of vibration is simple harmonic motion (SHM).
One system that manifests SHM is a mass, m, attached to a spring where k is

Newtons laws of motion
THEORY
Isaac Newton formulated his three laws of motion in the 1600s. These form
the foundation for understanding motion in the everyday world. Two new
concepts appear: force and mass.

Case one: Uniform circular motion [UCM]
To the ancient Greeks, uniform circular motion was considered the only
perfect form of motion. Today we study perfection!

The specific heat of a material will be different depending
on whether the measurement is made at constant volume or
constant pressure.

Phase Transitions; First Law of
Thermodynamics
Phase Transitions
All of us are aware of the three states (or phases) of matter: solid
(S), liquid (L) and gas (G). There are other, less common, states of
matter: superconductor, superfluid, and ferromagnet
Gravitational force and field
THEORY
In the seventeenth century Isaac Newton proposed the universal law of
gravitation, which states the gravitational force one point mass, M, exerts
on another point mass, m, when the two are separated by a distance, r, h
Gravitational Potential Energy
THEORY
Recall the change in potential energy of a system, V, is related to the work,
W, by the force one part of the system exerts on the other,
U - W = Wext
where Wext is the work by an external force against the gravity f

Thermal Expansion
A rod of length L will expand by L when its temperature
increases by T. It is found L is proportional to T,
L = L T,
where is the one dimensional thermal expansion coefficient.

An ideal gas consists of atoms that do not exert forces on each other and
