When It's Not Better to Throw at an Angle
Day, Lawrence
Teaching Science, v54 n4 p51-53 Dec 2008
For the case of objects thrown from an elevated position, students tend to believe an object thrown at an upward angle will always land farther away than one thrown horizontally at the same speed. That this is not always the case comes as a great surprise to many. By analysing the situation of a horizontally-thrown object outdistancing one thrown at an angle, students come to a better conceptual, as well as calculational understanding of projectile motion. After coming to appreciate the intricacies involved in this somewhat surprising situation, most students are particularly satisfied with their deeper understanding of the physics of such motion.
