Exploring kinematics graphs We know from GCSE: area under a velocity-time graph represents displacement gradient of a line on a velocity-time graph represents acceleration Mechanics gives us a great context for applying pure maths at AS and A level.

Exploring kinematics graphs Motion Graph Gradient Area Notes Displacement - time Velocity - time Acceleration Displacement Areas below the time axis represent negative velocity. v = 0 indicates a possible change in direction.

Exploring kinematics graphs Fit the cards onto the grid so that each column is a matching set.

What’s wrong with these statements? ‘The speed is the gradient of the displacement-time graph’. ‘‘If the acceleration is negative then the particle must be moving backwards’. ‘If the velocity time graph is horizontal the particle is not moving’.
