"Bolos & Trebuchets" Trailer

Students try to predict the path of a projectile by swinging it at the end of a rope and choosing how fast to swing it and when to release it, in order to make it fly highest and farthest. They also get to see how the weight of an object affects its flight. This relates to centrifugal force, weight, velocity, momentum, and Newton's three laws of motion. This video also includes one of Mr. Mac’s crazy stories, “Evil Mister Fred’s Invincible Machine,” to help students remember the lesson. Difficulty: Medium
