Generating (t,d) data to make a motion graph (1/3) (MHS)
We know that objects move in different ways. They go fast, they go slow, they speed up, they slow down, etc. The best way to get a picture of this motion is to look at a graph.
In math class, you've made a lot (x,y) scatterplot graphs. In physics, we'll do exactly the same thing, but with (time, distance) data. The plan is to have students move down the hallway in various ways (walking, running, crabwalking, etc) and generate graphs of their motion.
In order to make such a graph, you need a data table that has a time and a distance for each point during the motion. To accomplish this, we need to know where someone is and when they are at each point. We're going to use the timers in your cellphone and the tiling on this hallway to do it, and the next two slides will explain how.
