Circular Motion
- Velocity is always at a tangent to the circle. Even if the speed remains constant, the velocity is changing because it is accelerating.
vc = 2𝝿r/T
- Centrapetal Acceleration is always toward the centre of the circle.
- ac = mv2/r
- Centapetal Force is the Net Force, and is also always towards the centre of the circle.
Fc = mv2/r
