How can a particle travelling in a circular path have a constant speed but still be accelerating |
- Speed is a magnitude of velocity and is scalar - The particle is constantly changing direction throughout the circular - therefore it's velocity is constantly changing as velocity is a Vector - acceleration is the rate of change of velocity thus changes |

Calculating the force of a particle on a turnable |
78 revolutions per min Thus, frequency is 78/60 - w = 2π x f thus; 8.17 - F = mw^2r |
