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.,
constant v

Vector Algebra
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

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
Motion
If an object changes its position with respect to its surroundings with time, then it is called in
motion.
Rest
If an object does not change its position with respect to its surroundings with time, then it is
called at res
Kinematics of Two-Dimensional Motion
Vector Kinematics
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
Viscosity
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
Projectile Motion
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
