Question
Distinguish between centripetal and centrifugal force.
Solution
| Centripetal force | Centrifugal force | |
| 1. | It is the real force | It is the pseudo force |
| 2. | Centripetal force is directed along the radius of a circle towards the centre. | Centrifugal force is directed away from the centre of a circle along the radius. |
| 3. | `vecF = - mω^2 vecr` | `vecF = + mω^2 vecr` |
| 4. | It is regarded in an inertial frame of reference. | It is regarded in a non-inertial frame of reference. |
