fundamentals of physics THE LAW OF INERTIA The tendency of a
body to continue in its state of rest or of uniform motion in a
straight line even when some external unbalanced force is
applied is called Inertia. Mass is the measure of Inertia of a
body. Inertia is of two types namely:- 1. Inertia of rest 2.
Inertia of motion The force which a body possess due to combined
effect of mass and velocity is callled the Momentum. It is
defined as the product of mass and velocity. It is denoted by p
. p=m*v SI unit of Momentum is Kgm/sec NEWTONs LAWS OF MOTION:-
NEWTON,s FIRST LAW OF MOTION It states that a body will continue
in its state of rest or of Uniform Motion in a straight line
unless compelled by some applied unbalanced force to change of
rest or of Uniform motion. NEWTON,s SECOND LAW OF MOTION The
rate of change of Momentum of a body is directly proportional to
the applied unbalanced force and takes place in the same
direction in which the force acts. NEWTON,s THIRD LAW OF MOTION
To every action, There is an
