A speedometer shows that a cyclist is going 1 m/s in the 1st second, 2 m/s in the 2nd second, and 3 m/s in the 3rd second, as the cyclist continues straight south. How do you know the cyclist is accelerating?
Because the cyclist is going at a faster speed each second. Since the velocity is changing, the cyclist must be accelerating.
