Kinematics

Gaining further knowledge on kinematics we talked about position, distance, and displacement. First position is defined as a relative place in space and time. Distance can be defined as how far a person or a thing goes between positions. Lastly displacement is how far you go and in what direction. For instance, relative to your starting point, where you end up gives you your displacement. My example is the football boys. They run on and off the field multiple times. However, this does not mean that they have a high displacement number. By the end of the game the distance that they traveled will be very long, but not necessarily their displacement. Lets say that the position number 40 is in was his starting position. He goes in to the game, and comes out after just one play and stands in the same place as his starting position. This makes his displacement zero. If he came off and stood 3 meters away from his starting position that makes his displacement 3 meters.

  1. This is a really good example of explaining displacement. And since the displacement is 0 then the vector is 0 as well.
