Kinematics in One Dimension
Kinematics deals with the concepts that
are needed to describe motion.
Dynamics deals with the effect that forces
have on motion.
Together, kinematics and dynamics form
the branch of physics known as Mechanics.

Nature of Electromagnetic
Waves
In our earlier discussion of heat we defined
Radiation as the process in which energy is
transferred by means of Electromagnetic Waves.

Kinematics
8.1 Rotational Motion and Angular Displacement
In the simplest kind of rotation,
points on a rigid object move on
circular paths around an axis of
rotation.

9.1 The Action of Forces and Torques on Rigid Objects
In pure translational motion, all points on an
object travel on parallel paths.
The most general motion is a combination of
translation and rotation.

4.1 The Concepts of Force and Mass
A force is a push or a pull.
Contact forces arise from physical
contact .
Action-at-a-distance forces do not
require contact and include gravity
and electrical forces.

Electromotive Force and
Current
An electric current is any motion of charge from one region of a conductor to
another.
This electric current is defined as the amount of cha
