P2- motion

distance time graphs

  • used to help describe motion of an object
  • distance (y axis) time taken (x axis)
  • speed of an object is distance travelled each second (distance/time)
  • gradient of the line on a graph indicates the speed, steeper gradient=faster
  • if an object is stationary the line is horizontal
  • a straight line that slopes upwards shows the object moving at a constant speed

velocity and acceleration

  • velocity is speed in…
