Velocity-time graphs

Velocity-time graphs

Velocity-time graphs provide a useful way of displaying the motion of an object.

They can be used to:

1)    Describe the motion of the object in detail.

2)    Calculate values for accelerations and decelerations using gradients.

3)   Calculate distances travelled and resultant displacements using area under graph.

4)    Calculate the average velocity for a journey.

(Note: Speed-time graphs are also used, but a speed-time graph would not show any change in direction).
