Motion along a straight line

In the equations below;

  • v = velocity in metres per second (ms-1)
  • Ds = change in displacement in metres (m)
  • Dt = change in time in seconds (s)
  • a = acceleration in metres per second per second (ms-2)

velocity equation

acceleration equation

In the equations below;

  • v = final velocity in metres per second (ms-1)
  • u = initial velocity in metres per second (ms-1)
  • a = acceleration in metres per second per second (ms-2)
  • t = time in seconds (s)
  • s = displacement in metres (m)
