Introductory Conservation of Mechanical Energy Problem using a Trebuchet

Learn how to use the Conservation of Mechanical Energy equation by solving a trebuchet problem. Want Lecture Notes? http://www.flippingphysics.com/coe-pr... This is an AP Physics 1 topic. 0:00 Intro 0:08 The problem 1:08 Why mechanical energy is conserved 1:37 Setting the zero line and initial and final points 2:32 The three types of mechanical energy 3:55 Canceling mechanical energies from the equation 4:54 Solving the equation 6:18 It’s final speed not final velocity 6:51 Why we can’t use the projectile motion equations 7:43 Do we really have to write all that down? Yes. Thank you to my students Will, Jacob, Natalie and Mery; my students who built and let me use their trebuchet!
