3 Notebook set up Date: Daily work: IN: Objective: Success Criteria: Synthesis PictureI own this I still don’t understandthisOUT:5Daily work:6
4 In:If an 200 kg object reaches the top of a 10 m hill, how much potential energy does it have? How much work will it do to go down the hill? How much power will be exerted when if it takes 5 seconds to go down the hill?
5 Goals:Objective: apply the laws of thermodynamics to determine how energy is conservedSuccess Criteria:Be able to:- describe where energy is present in each form- explain how energy is conserved using quantitative data- describe why a roller coaster works using these laws
7 Fundamental Laws Law Simple Name of the Law Description Example First Law of ThermodynamicsSecond Law of ThermodynamicsThird Law of ThermodynamicsConservation of MassWhat is energy? What does it do?
8 ThermodynamicsEnergy is the ability to bring about change or to do work.First Law of Thermodynamics: Energy is always conservedSecond Law of Thermodynamics : Energy flows from high to lowSecond Law of Thermodynamics : Movement decreases as energy decreases but never completely stops
14 Background Information Describe which law each question is referring toExplain why that is the most appropriate using your knowledge and vocabulary from Newton’s Laws
15 Roller Coaster Challenge You must analyze the physics of a roller coaster from through the lens of work, power, and energy. To do this you will have to rely on your knowledge of energy to determine the best design for a roller coaster.
16 If you destroy any of the materials they will not be replaced Grades will be on successful design AND explanations You must present your idea (drawing and explanations) prior to initiating construction
17 BackgroundFrom your reading write a summary paragraph which will help you to answer the questions in your challenge(Be sure to include the necessary equations and explanations to determine the necessary structural designs)
18 Synthesis:Something creative…A drawing, a diagram, a question, a sentence that represents your thinking from this class period.
