Students explore the vertical and horizontal components of projectile motion in this laboratory investigation using ramps, time trials, and a three man slingshot. Topics include trajectory motion, acceleration due to gravity, speed, and velocity. Includes guided calculations and encourages the use of calculation to predict apex and landing. After learning the basic concepts, students go outside and collect data using water balloons and a three man sling shot! Allow two 45 minute lab periods for conducting experiments and additional class time for calculations. Appropriate for any level physics course (including AP) or general science courses. Designed for working in groups of four to six, with materials sufficient for up to 36 students.
