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
