Presentation Transcript

  1. Circular Motion. Learning objectives; To know that an accelerating object can be undergoing a change in direction without the speed changing. (Grade D/C) To understand that centripetal force acts towards the centre of a turning circle. (Grade C/B) To explain the factors that affect centripetal force. (Grade B +)

  2. Tasks; Use pages 236-237. • Explain fully (with help of a diagram) what centripetal acceleration is. Explain why it is an “acceleration” despite the fact that speed may not change. • Explain why we call the force on a spinning object centripetal force, and not centrifugal. • Write down a discussion of the FACTORS affecting centripetal forces AND explain how these factors affect some everyday examples (eg cars, the cup experiment etc) • Attempt ALL summary questions. • Extension = page 241, exam questions (in full).
