Genaral information on “Circular motion”
The same rules apply for the acceleration, the distance and the velocity on the circular path that the one for a linear accelerated motion.
More informations – formulas in compare:
| linear motion | circular motion |
| distance-time-rule | Rotation angle-time-rule |
| s = ½ · a · t2 | φ = ½ · α · t2 |
| s = ½ v · t | φ = ½ ·ω ·t |
| velocity-time-rule | velocity-time-rule |
| v = a* t | ω = α · t |
| v = a √ ( 2 · s / a) | ω = α √ ( 2 · s / α ) |
| s | distance on the circular path | m |
| v | velocity on circular path | ms –1 |
| a | acceleration on circular path | ms-2 |
| φ | angle of rotation | rad |
| ω | angular speed | rad s-1 |
| α | acceleration of rotation | rad s-2 |
| t | time | s |
| r | radius of circular path | m |
