In this experiment, students will be using a projectile launcher to release a piece of cork ( the projectile) at different angles. The launcher provides the initial thrust force and a built-in protractor to measure the angle of release. Students will be investigating and determining the angle of release to discover, which will provide the furthest launch distance. Students will launch their projectile three times at 5 different angles: 15º, 30º, 45º, 60º, & 75º and calculate the average to determine the best release angle. Teachers need to have some sort of projectile launcher for this lab. I used a spring loaded launcher made of PVC and wood, which I had the angles on. This is a perfect lab for students to build an understanding of vertical and horizontal motion of a projectile.
