Example 1: completing a speed-time graph. The speed-time graph shows the speed of a car for the first 1010 seconds of a journey. After the first 1010 seconds the car maintains its speed for 2020 seconds. It then decelerates at a constant rate and stops after a further 1515 seconds.

A: The graph line for this runner during seconds 0–4 would be steeper (have a greater slope). This would show that acceleration is greater during this time period for the other sprinter. Use the following PLIX Interactive to predict what the velocity-time graphs will look like for three baseballs accelerating at different rates:
The slope of the speed-time graph will give the magnitude of acceleration (k). Case 3: Speed-time graphs with increasing acceleration. When the acceleration increases with time, the speed time graph will be a curve, as predicted from the equation: v = u + at. Since u = 0. v= at. Since acceleration is a function of time, the speed time graph ...
Speed–time and velocity–time graphs both give information about the motion of an object that is accelerating. The graphs below both represent the motion of a ball after it has been thrown vertically upwards with an initial speed of 15 m s –1. The speed–time graph shows that the speed decreases to zero as the ball reaches its maximum ...
