1. MOTION, FORCES AND ENERGY 1.2. Motion Speed is defined as the distance travelled per unit time. Use the equation v = d Where: 1.1. Physical quantities and measurement techniques v is speed d is distance t is time Velocity is defined as the speed in a given direction. Liquids: A graduated measuring cylinder. A pipette (accurate for one specific measurement) Time: Stopwatch (reading to 0.1s or better) Length: Metre rule (graduated in mm) Micrometer Screw Gauge Vern...

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
