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?

Objective: apply the laws of thermodynamics to determine how energy is conserved

Success 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

Law Simple Name of the Law

Description Example

First Law of Thermodynamics

Second Law of Thermodynamics

Third Law of Thermodynamics

Conservation of MassWhat is energy? What does it do?

Energy is the ability to bring about change or to do work.

First Law of Thermodynamics: Energy is always conserved

Second Law of Thermodynamics : Energy flows from high to low

Second Law of Thermodynamics : Movement decreases as energy decreases but never completely stops

Roller Coaster Physics

http://www.britannica.com/coasters/ride.html

http://www.myphysicslab.com/RollerSimple.html

Describe which law each question is referring to

Explain why that is the most appropriate using your knowledge and vocabulary from Newton’s Laws

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.

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

From 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)

Something creative…A drawing, a diagram, a question, a sentence that represents your thinking from this class period.

I own this: I still don’t understand this:

Explain how do the laws of thermodynamics apply to energy conversions.
