Day 2.24 Using v vs. t Graphs to Quantitatively Analyze Accelerated Motion

This isn’t the best picture to show it, but we quizzed on using quantitatively accurate v vs. t graphs to analyze accelerated motion.  We have not derived any of the standard kinematic motion mathematical models.  With the exception of defining acceleration as change in velocity over a change in time.  All problem solving is being done with the understanding that the slope of a v vs. t graph is the acceleration and the area under the graphed line is the displacement.  From here it is just using simple algebra and/or some basic geometry.

I much prefer this approach over the standard plug and chug of equations.  I feel the students get a much better sense of what they are solving for and how to relate the actual motion of an object to the numbers we are solving for.
