Circular Motion

  • Circular motion means velocity is constantly changing
  • Velocity is the speed and direction of an object.
  • If an object is travelling in a circle it is constantly changing direction, which means it's accelerating.
  • This means there must be a force acting on it.
  • The force is acting towards the centre of the circle.
  • This force is called the centripetal force.
  • The force which gives the centripetal force can be friction, tension or gravity.
  • For a car going
