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
