Apologia Physics: Catapults or Projectile Motion Module 5

Module 5 topic is projectile motion.  Today we built a trebuchet and a catapult.  We fired a projectile, a ping pong ball, from the catapult and recorded the motion with Verneer's video app.  During the next class we will analyze the videos, graph the projectile movement, and separate the forces that act upon the ping pong ball, horizontal and vertical.  The paper trebuchet worked but did not send a projectile, a paper clip, more than a foot at best so we will not use that data but what we built will serve as a good model.
