Centripetal Acceleration & Circular Motion

URL Original: http://plabpc.csustan.edu/general/tutorials/CircularMotion/CentripetalAcceleration.htm

The simulation below the position of a car which is being driven at constant speed around a bend in the road. When the car is travelling along the straight sections of the road its velocity is a constant. Hence there is no acceleration. However, when is being steered around the corner its velocity changes even though its speed is a constant. There is an acceleration directed towards the centre of the circle, called the centripetal acceleration.
