Let me start with a graph. This shows the horizontal acceleration of the pod as a function of time. Here the pod accelerates at 9.8 m/s 2 for 2.6 minutes and then travels at a constant speed.

These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still. Acceleration is shown by a straight rising line. Deceleration is shown by a straight ...

Save guides, add subjects and pick up where you left off with your BBC account. The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time.

Here is a plot of the horizontal velocity of the spore. Since the average acceleration is defined as: The slope of the velocity-time graph is the average acceleration. You can see the fitting ...
