• Resumen

  • 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.
