Kinematics: Motion of a Particle in One
and Two Dimensions
For now, we consider objects that have masses but
of infinitesimal sizes, i.e., the Particle Model
2.1 Motion in One Dimension (1D)
Dynamic variables describing the motion in 1D
include

Force, Newtons Laws of Motion
Newtonian Mechanics is based on the laws
presented by Isaac Newton (1642-1727).
However,
at very large speeds (an appreciable fraction of the
speed of light c), Newtonian mechanics must be
replaced by Einsteins spec
Chapter 4
Circular and Curvilinear Motions
Here we consider particles moving not along a straight line
the curvilinear motion. We first study the circular motion, a
special case of curvilinear motion. Another example we have
already studied earlier is th
Chapter 5
Work and Energy
We deal with the physical System, a portion of the universe,
separated from its environment by a boundary (not necessarily
physical surface).
5.1 Work
By a constant force F :
W = F r = F r cos
The Unit of work is joule (J) = ne

Linear Momentum, Collision &
Center of Mass
p = m v (linear momentum of a particle)
Linear momentum is a vector and the SI unit is kg-m/s.

Rotation of Rigid Body
A rigid body is one that is nondeformable, i.e., the relative
positions of all particles making up
the object remain constant during
its motion.
It is much more convenient to work
with angular position, velocity and

Simple Harmonic Motion (SHM)
8.1 Equation of Motion
A vibrating system for which the restoring force is directly
proportional to the negative of the displacement ( F kx) is said
to exhibit Simple Harmonic Motion (SHM), and the system is
referred
