Question
Explain the terms inertial and non-inertial frame of reference.

Answer
Inertial frame of reference: - A frame of reference in which Newton ‘s first law of motion is applicable is called inertia/frame of reference. - A body moves with a constant velocity (which can be zero) in the absence of a net force. The body does not accelerate. - Example: A rocket in inter-galactic space (gravity free space between galaxies) with all its engine shut.
Non-inertial frame of reference: - A frame of reference in which an object suffers acceleration in absence of net force is called non-inertial frame of reference. - The body undergoes acceleration. - Example: If a car just start its motion from rest, then during the time of acceleration the car will be in a non-inertial frame of reference.
