Question

what is inertial frame and non inertial frame explain it long

Answer 1

: An inertial frame of reference is a frame that is moving at a constant velocity.

This means that the acceleration of the frame of reference is zero.

A non-inertial frame of reference is just the opposite: it is a reference frame that is undergoing a nonzero acceleration.it using a non-inertial reference frame can still be useful in the right scenarios.[/tex]

Answer 2

In simple words inertial frame means that the reference frame of observer is at rest, for example a man on ground observing upward motion of a lift. Non-inertial frame means that the reference frame of observer is in motion, for example a man sitting inside the lift and observing something.
