AQA A A2 PHYSICS- CIRCULAR MOTION

CIRCULAR MOTION

Radian- the angle subtended at the centre of the circle by an arc of the circle, whose length is equal to the radius of the circle.

Angular displacement- the angle moved through relative to a specific axis.

Angular velocity-the rate of change of angular displacement with time.

Centripetal Acceleration

Objects moving in a circle have changing velocity, which is always along the tangent of the circle. Any moving object at constant acceleration has a centripetal force acting on it. 

Examples of centripetal forces:

• Jupiter obiting the sun has a centripetal force of gravitational…
