A horizontal line means the object is moving at a constant ... speed. The steeper the line, the greater the increase in speed. The area under the graph = the distance travelled. This is a speed ...

They are afraid to embrace the power of the graph. OK, let's do a simple experiment and use a graph to find a mathematical model. Constant ... methods to collect position-time data then there ...

During that time ... a constant acceleration. Finally, let me leave you with just one homework assignment. See if you can create the same (or at least very similar) position vs. time graph ...
