What is physics?
basic physics of motion where the object (race car, tectonic plate, blood cell, or any other
object) moves along a single axis. Such motion is called one-dimensional motion.
The classification and comparison of moti

Definition of a Vector
A vector v is determined in terms of its magnitude v = |v| and its direction vb = v/v. In twodimensional space, a vector v is written as
v = vx xb + vy yb,
where xb = (1,0) and yb = (0,1) are unit vectors in the dire

Equilibrium Between Matter and Radiation
Imagine a closed oven, maintained at a constant temperature, To. Inside, E-M waves bounce
from wall to wall, being absorbed and re-emitted over and o
Forces due to Friction and Uniform Circular Motion
In the present Lecture Notes, we investigate new types of force: forces due to friction
and forces due to uniform circular motion.
Forces due to Friction
Properties of a friction force (labeled Ffr) are

MOTION IN A STRAIGHT LINE
If an object changes its position with respect to its surroundings with time, then it is called in
If an object does not change its position with respect to its surroundings with time, then it is

Kinematics of Two-Dimensional Motion
Kinematics is the part of Physics that contains the terminology used to describe the
motion of particles. For this purpose, the first element of the kinematic description of the
motion of a particle
MECHANICAL PROPERTIES OF FLUIDS
The property of a fluid by virtue of which an internal frictional force acts between its different
layers which opposes their relative motion is called viscosity.
These internal frictional force is called viscous
The problem of projectile motion involves the kinematic description of the path of an
object (the projectile) moving in the presence of the constant gravitational acceleration a =
g yb, where g = 9.8067. m/s denotes the standard value of
Newtons Laws of Motion
Newtons First Law of Motion
A body continues in its state of rest or of uniform linear motion until it
is acted upon by a net force.
The tendency of a body to maintain its state of rest or of uniform linear motion (i.e.,
