Question
Distinguish between inertial and non-inertial frames of reference.
Distinguish Between
Solution
| Inertial frame of reference | Non-inertial frame of reference | |
| 1. | The body moves with a constant velocity (can be zero). | The body moves with variable velocity. |
| 2. | Newton’s laws are obeyed. | Newton’s laws are not obeyed. |
| 3. | The body does not accelerate. | The body undergoes acceleration |
| 4. | In this frame, a force acting on a body is a real force. | The acceleration of the frame gives rise to a pseudo force. |
| 5. | 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 noninertial frame of reference. |
