Unformatted text preview: Since v is perpendicular to r A is perpendicular to v So a is towards the centre of the circle(centripetal) o In general, direction and speed both change V has components parallel and perpendicular to motion and a = delta v / delta T Radial is a component is due to the change in direction Tangential component is equal to the rate of change of speed-Bicycle and wasp question o...
