Newton's first Law or regulation states that each and every object will continue to be at rest or in uniform motion in a straight line except compelled to alternate its nation by using the action of an external pressure this is commonly taken as the definition of inertia .

Sir Issac Netwon has given three laws to describe the Motion of an object.

Newton's First law of motion states that " Every body continues to be in it's state of rest (or) uniform motion in a straight line unless it is acted upon by a net external force to change that state " . This law defines ' inertia ' , ' Force ' and mechanical equilibrium .

Some Terms Related to First law :

(i) Force

" Force is a pull (or) push which changes (or) tends to change the state of rest (or) of uniform motion "

(ii) Inertia

It is the inability of a body to change it's state of rest (or) of uniform motion (or) it's direction by itself. Mass is the measure of inertia . Heavier the mass , Larger the inertia and vice versa .

Inertia is of three types ,

  1. Inertia of rest
  2. Inertia of motion
  3. Inertia of direction

(1) Inertia of rest

It is the inability of a body to change it's state of rest by itself .

EXAMPLE : Passengers in the bus , jèrk backwards when the bus suddenly starts

(2) Inertia of motion

It is the inability of a body to change it's state of uniform motion by itself .

EXAMPLE : When the fan is switched off , it continues to rotate for a while due to inertia of motion

(3) Inertia of direction

It is the inability of the body to change it's direction of motion by itself .

EXAMPLE : When a bus takes a sudden turn passengers in it experience an outward force.
