J. Edwards, Ph.D.
Below are some of the mathematical concepts that you have certainly seen before and therefore
is required knowledge in a college Physics course. This document is intended to provide you with
a brief overview of the concepts y

Introduction
Near the surface of the earth (or any other planet for that matter), the acceleration due to gravity
is nearly constant over the planets surface. You can compute the gravitational attraction b
Work, Kinetic Energy and the Work-Kinetic Energy Theorem
J. Edwards, Ph.D.
The motion of any object can be completely described if the forces acting on it are known;
however, this method of predicting motion may not be desirable. When the forces acting on

Friction Force
The normal force is one component of the contact force between two objects, acting
perpendicular to their interface. The frictional force is the other component; it is in a
direction parallel to the plane of the

Projectile Motion with Air Resistance
J. Edwards, Ph.D.
Including air drag is a complicated task in physics. That is why for most physics problems
it is neglected. However, it is important to understand that air drag is always present and can
cause some p
Moment of Inertia
J. Edwards, Ph.D.

Introduction
The moment of inertia (MOI) of a rotating object (also called the mass moment of inertia) is a measure
of an objects resistance to changes in its rate of rotation. It is the rotational counterpart of mass
