Just like any other dog, my dog Cujo loves to go for walks. The only problem being that half the time he ends up running after something and I get dragged along for a couple seconds. I never really thought about it before, but Physics can explain a lot of the things that occur when Cujo and I go for our walks.
When we are traveling at a normal pace, I can determine our average velocity by taking our distance and dividing it by how long we have been traveling. But what if Cujo happens to see the neighborhood cat? Of course he's going to take off after it and try to drag me along with him. I can then calculate our average velocity and see that it had increased because we went such a huge distance in a short period of time.
