linear motion 0.0 / 5 ? Physical EducationBiomechanicsA2/A-levelOCR Created by: NiamhMFCreated on: 28-11-17 10:39 Movement of a body in a straight (or curved) line, all parts move the same distance in the same direction. linear motion 1 of 9 A force applied through the centre of mass. direct force 2 of 9 The point at which a body is balanced in all directions. Weight appears to act. centre of mass 3 of 9 Length covered from start to finish (m). distance 4 of 9 Shortest straight-line route from start to finish (m). displacement 5 of 9 Calculated using distance/time taken. Measured in m/s. speed 6 of 9 Calculated by using displacement/time taken.Measured in m/s. velocity 7 of 9 Calculated by using (final velocity-initial velocity)/time taken. Measured in m/s/s. acceleration 8 of 9 Rate of change (decrease or negative) in velocity. Measured in m/s/s. deceleration 9 of 9
