• 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.
