### Transcript of "Cm 4 the conical pendulum (shared)"

1. 1. A-level PhysicsUnit G484:The NewtonianWorldExamples ofcircular motionCircular motion
2. 2. Moving in a circle LOsWhat provides thecentripetal force ineach of thesesituations? The Moon in orbit around Cornering on a perfectly the Earth. banked surface. Protons moving around the LHC. Cornering on a horizontal surface.Circular motion
3. 3. Lesson focus • Identifying the origins of centripetal force Learning objectives At the end of the lesson you will be able to: • use the equation for centripetal acceleration a = v2/r ; • use the equation for centripetal force F = ma = mv2/r ; • identify and quantify centripetal force in a variety of situations.Circular motion
4. 4. Learning outcomes All of you should be able to • quantify centripetal forces for simple situations in which objects move in horizontal circles. Most of you will be able to • describe the variation of centripetal force on the surface of a spinning sphere. Some of you may be able to • describe the origin and variation of centripetal forces for motion in vertical circles.Circular motion
5. 5. Conical pendulum LOs To do Explain the motion of the conical pendulum Things to think about: • What forces act on the pendulum? • What is the vertical motion of the pendulum bob? • Can you write an equation to describe the vertical forces? • What provides the centripetal force?Circular motion
6. 6. Conical pendulum LOsCircular motion
7. 7. Conical pendulum LOs T Questions 1. Resolve T into horizontal and vertical components (TH and TV respectively). Label TH and TV in terms of T and . 2. What provides the centripetal force here?Circular motion LO 2: use the equation for centripetal force
