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 ...
- The speed of a body in a specific direction is the measure of Velocity. Rate of change in displacement with respect to time is known as velocity. V...
- Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and n...
- There are four types of speed and they are: Uniform speed Variable speed Average speed Instantaneous speed
- When an object is moving with variable speed, then the speed of that object at any instant of time is known as instantaneous speed.
- Average velocity is a vector quantity. Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t...
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 ...
