Tuition Center Singapore Physics Tuition – Kinematics Definitions Displacement is the measurement of distance from a reference point to another point in a certain direction. The SI unit of displacement and distance is metre (m). Velocity is the rate of change of displacement. Speed is the rate of change of distance. Velocity is a vector quantity whereas speed is a scalar quantity. Speed is the magnitude of velocity. The SI unit of velocity and speed is metre per second (m/s or m s-1). For constant speed, its value is given by: Speed  =  distance travelled / time taken           For non-constant speed, the average speed is given by:           Average speed = total distance travelled / total time taken.   Please contact Mr Ong @ 9863 9633 or Angie @ 96790479 if you need help in O ...
