Getting Rid of Gravity--Alternative Ways of Looking at Trajectories
Dion, Peter W.; Ho, Anthony M. H.
Physics Teacher, v48 n4 p258-260 Apr 2010
Problems in projectile motion are a time-honored staple of high school and even first-year university physics. They can become confusing for some students, yet boring for the stronger students. Herein we present two alternative approaches to such questions, one we call "breaking down gravity," which makes these questions easier to solve, and the other we call "getting rid of gravity," which converts such questions into a more interesting and challenging form.
