Unit 7. Motion in a circle


A Level


9m 59s
The turning effect of forces is introduced in Topic 5. In this topic, rotational motion, confined to motion in a circle, is studied. Radian measure is introduced and equations for circular motion are developed, in terms of both angular and linear speeds. The key areas of content being discussed are: Kinematics of uniform circular motion, Centripetal acceleration and centripetal force
