Rollercoaster Project This project is designed to teach you about applications of KE, PEg, and the Conservation of ME. You will build a “working” rollercoaster with at least 3 “features” to it. “Working” means that a marble/car will successfully travel along the entire course of the coaster under it’s own energy when released from a starting position A “feature” may be: a hill or initial drop, a loop (sideways or vertical), a corkscrew (sideways or vertical), or a jump. If you want to include a different item in your track as one of your 3 “features”, you must get it approved through me first. After building the coaster you will calculate your “car’s” (may be a marble or ball bearing) ME (KE + PEg) at the highest point(s) of each of your 3 features and the end point. Calculate your “car’s” speed at the bottom of the biggest drop Assume no friction is present and therefore ME is conserved

Tuesday Bellwork Prepare 1. Prepare your desk and mind for the Chapter 4 Quest! 2. You 2. You may have: 1.Blank 1.Blank scratch paper 2.Calculator 3.Pencil 3.Pencil (#2) for scantron

Objectives 1. TSW 1. TSW display personal mastery of Newton’s Laws and their implications on everyday forces

Tuesday Class Plans  Take chapter 4 Quest  HW: Finish Friction Lab if not already done: Only Results and Analysis questions (1 per two people)
