Warning: Although the word equation helps with making conceptual sense of what's going on with velocity, it doesn't capture everything we are thinking about when we talk about velocity. (We show the icon of the dog here since we want you to "make sense" of the velocity equation, pulling the picture of the spotted dog out of a picture with lots of spots. That way, doing either a bigger distance in the same time or the same distance in a shorter time both give a larger number to the velocity and agree with our sense of what it means to move faster. To make sense out of this, let's first write it as a words equation:Īverage velocity = (How far did you move?) / (How long did it take you?) Velocity is the answer to the question: How fast are you changing your position? It's basically asking for a comparison of where you are at two different times and makes the rate of change quantitative.
