Now that we've talked about the four major models of mechanics, we started projectile motion through video analysis. We immediately saw that the difference in the x-component of the motion and the y-component of the motion. Ut made sense using forces. Energy seemed like an easy way to figure out velocities. And momentum didn't seem useful at all.
We tried a problem about hang time. Two solutions are presented below. Almost every student liked the graphical way and didn't like the equation (which worked & which they learned in math class).
