Graphical Method for Determining Projectile Trajectory

We present a nontrigonometric graphical method for predicting the trajectory of a projectile when the angle and initial velocity are known. Students enrolled in a general education conceptual physics course typically have weak backgrounds in trigonometry, making inaccessible the standard analytical calculation of projectile range. Furthermore, research shows that standard instructional techniques fail to confront student misconceptions about motion in a gravitational field. We have designed a guided inquiry-based lesson that specifically addresses these misconceptions with minimal mathematics.
