Learned by: making graphs, tables, and functions.
Thing learned: coming up with speed per unit
Learned by: delta position divided by delta time or x2-x1/t2- t1
Thing learned: when two things are a certain distance apart
Learned by: making tables and/or graphs
Thing learned: relationship between speed and velocity
Learned by: |v|= speed
Thing learned: "dot diagrams suck"
Learned by: they don't tell you enough about the motion of an object
Thing learned: making motion diagram
Learned by: doing problems like the one with the motorcycle and the moon. You can make one by adding arrows, an origin, positive and negative directions, and labeling ( V1, V2 ect.)
It is important to know these things so that you can read graphs and describe motion. If you know this than you will be able t accurately display data to anyone who wants to read it. You can show it better than a dot diagram or picture. Scientists use this information to make roads and speed limits. You also need to know this if you are a pilot (when two planes will collide) or astronauts. If you are making cars you need to know this stuff. And if you are coming up with a speed limit you need to make sure that cars will not flip over or skid when making a turn.
