Question

define inertial and non inertial frame of reference with example

Answer 1

Inertial Frame of reference or Unaccelerated Frames

A Frame of reference in which the bodies obey Newton's laws of motion is called an inertial Frame

Non Inertial Frame of reference or Accelerated Frames

A Frame of reference in which Newton's laws of motion are not valid is called a non Inertial Frame

Answer 2

Inertial references frames :-

inertial reference frames in which Newton first law of motion holds i.e. an object at rest and an object in motion remains motion unless acted by a net force. An inertial reference frame is either at rest or moves with a constant velocity.

Example - A train moving with constant velocity.

Non inertial reference frames :-

non−inertial reference frame is a reference frame that is accelerating either in linear fashion or rotating around some axis.

Example - A turning car with constant speed.
