What is happening (at constant speed):
- The velocity is directed to the tangent of the circle.

Grade A
What is happening:
- The change in velocity is towards the centre of the circle.

If the object is constantly changing its velocity, therefore it is said to be ACCELERATING towards the centre of the circle – called centripetal acceleration.

Grade A
Therefore, resultant force is towards the centre of the circle – called centripetal force.

Grade B
To be able explain the factors which affect centripetal force
Grade A
Other examples:- Car going around a roundabout –
centripetal force is due to friction between tyres and road.
- Satellite going around the Earth. - Hammer thrower at the Olympics.- Fairground ride centripetal force at
the top is due to weight.

What affects the centripetal force?
- Speed = faster the object, the greater the centripetal force needed.
- Radius = centripetal force increases as radius decreases. Harder to keep an object in a circle with a SMALL radius.
