what is the difference between circular motion and periodic motion?? Pls give two examples with it.
Your friends have given the examples here I give the differences only.
Differences between circular and periodic motion.
| Circular motion | Periodic motion |
1. | All circular motions are periodic | All periodic motion are not circular |
2. | The distance from the centre is constant | The distance from centre may vary with time. |
3. | The radial acceleration is always present and is directed towards the centre | May not be always directed towars the centre. In general radial acceleration may be absent. |
