Draw a vector diagram to illustrate that the acceleration of a particle moving with constant speed in a circle is directed towards the centre of the circle. CENTRIPETAL ACCELERATION: The acceleration of a body moving in a circle. It is directed towards the centre of the circle. A body with a centripetal acceleration must be under the influence of a centripetal force.

Apply the expression for centripetal acceleration. Identify the force producing circular motion in various situations. Examples include gravitational force acting on the Moon and friction acting sideways on the tyres of a car turning a corner. Solve problems involving circular motion. Problems on banked motion (aircraft and vehicles going round banked tracks) will not be included.

Furthermore, if the angle is very small, then the acceleration is perpendicular to v 1 and v 2, ie directed towards the centre of the circle.
