1. Motion in a Circle 1.1. Radians Radian: one radian is the angle subtended at the center of the circle by an arc of length equal to the radius of the circle Angular displacement: the angle through which an object moves through a circle Hence 1 revolution is 0.1sec Use angular velocity formula 2π ω = 0.1 = 62.8 Using relation between angular and linear velocity v = ωr = 62.8 × 0.2 = 12.6 ms-1 1.3. Circular Motion s = rθ

CIE A'level Physics 9702 A2: Medical Physics Explain the main principles behind the GENERATION of ULTRASOUND to obtain diagnostic information about internal structure. - ~ Use piezo-electric crystal ~ two sides coated with silver act as electrodes ~ centres of (+) & (-) charge do not coincident. ~ p.d. across crystal causes crystal to change shape ~ alternating voltage applied across crystal causes crystal to vibrate. ~ so that it vibrates at resonant frequency Ultrasound to obtain dia...

These are the full revision notes which cover all topics required for the (CAIE ) Cambridge AS and A Level Physics exam. They cover all the theory parts required by the syllabus for the AS Paper 1 (Multiple Choice) and AS Paper 2 (AS Structure Questions) and A2 Paper 4 (AL Structure Questions). The syllabus code is 9702. Please try these notes and good luck with your exams! I recommend them as I got A* in my full A level Physics. If you have any doubts don't hesitate in contacting me!
