Now that we have seen how distance and displacement are different numerically, let us understand the same graphically.
Look at the graph alongside and choose the right option. The graph plots the position of an object on the y-axis and the time on the x-axis.
  • The object started from rest, reached a maximum velocity of \(20 \, \mathrm{m/s}\) and then returned to rest
  • The object started from rest and covered a total distance of \(20 \, \mathrm{m}\) in \(4 \, \mathrm{s}\)
  • The object's final displacement was \(40 \, \mathrm{m}\): \(20 \, \mathrm{m}\) in the first \(2 \, \mathrm{s}\) and \(20 \, \mathrm{m}\) in the next \(2 \, \mathrm{s}\)
  • The object reached a displacement of \(20 \, \mathrm{m}\) in \(2 \, \mathrm{s}\) and then came back to the original point, with a final displacement of \(0 \, \mathrm{m}\)
