Question
distinguish between:
Inertial and non-inertial frames of reference.

Answer

Inertial and non-inertial frames of reference.
No. Inertial frame of reference Non-inertial frame of reference
i The body moves with a constant velocity (can be zero). The body moves with variable velocity.
ii. Newton’s laws are Newton’s laws are
iii. The body does not accelerate. The body undergoes acceleration.
iv. In this frame, force acting on a body is a real force. The acceleration of the frame gives rise to a pseudo force.
Example: A rocket in inter-galactic space (gravity free space between galaxies) with all its engine shut. Example: If a car just starts its motion from rest, then during the time of acceleration the car will be in a non- inertial frame of reference.
