Reading a velocity-time graph

Reading a velocity-time graph.

  • A velocity–time graph shows velocity vertically and time horizontally.
  • Its gradient gives acceleration; its signed area gives displacement.
  • For distance, add the magnitudes of areas if the graph goes below the time axis.

Example 1

State the maximum velocity and the interval during which velocity is constant.

Constant intervalA horizontal velocity–time segment means constant velocity, not rest unless .
Maximum velocity 12 ; constant from 2 s to 4 s.

Example 2

State the maximum velocity and the interval during which velocity is constant.
