form 4- 32 circular motion - kcpe-kcse
... NOTE: This is not required for A2 AQA Physics Consider an object moving at constant speed, v from point A to point B along a circular path of radius r. Over a short time period, δt it covers arc length, δs and sweeps out angle, δθ. As v = δs / δt then δs = v δt. The velocity of the object changes in ...

... point, is simply 0. If you refer to the notes for Lecture 17 you will see that the constant term does depend on the charge density λ, thus it will change sign if λ changes sign. IF we have a system of two very long wires having equal but opposite charge densities ±λ we can use superposition to calcu ...
