After this lesson, you should be able to:

• Describe the motion of an object in words, given its position-time, velocity-time or acceleration-time graph
• Determine the velocity of an object from the gradient of its position-time graph
• Work out instantaneous velocities at particular times using the position-time graph
• Determine the acceleration of an object from the gradient of its velocity-time graph
• Determine the displacement of an object from the area under the velocity-time graph
