Unit Test Review Forms of Potential Energy 1.Name the Five Forms of Potential Energy. 2.Explain when each form is storing energy. (Describe the forces involved.) 3.Which of the forms of Potential Energy can you calculate an actual amount.

Unit Test Review Forms of Kinetic Energy 1.Name the Five Forms of Kinetic Energy. 2.Explain when each form has kinetic energy. (Describe what is moving.) 3.Which of the forms of Kinetic Energy can you calculate an actual amount or change.

Unit Test Review Law of Conservation of Energy State the complete Law of Conservation of Energy. Check your answer with what is written in the glossary of your book

Unit Test Review Law of Conservation of Energy Critique the following statement: “If one drops a book, that book obviously loses energy when it reaches the floor. Therefore, the law of conservation of energy is incorrect.”

Unit Test Review Mechanical Systems What forms of energy do we take into consideration when we discuss mechanical systems that are 100% efficient?

Unit Test Review Work – Energy Theorem 1.What does the work- energy theorem state? 2.Can work have positive or negative values? 3.The work done on a ball to make it roll is positive/negative work. 4.The work done by a ball to bring it to a stop is positive/negative work.

Unit Test Review Work – Energy Theorem 1. Use the work- energy theorem to describe the energy transfer of a ball getting a push and then rolling to a stop. 2. Draw energy diagrams of the ball.

Unit Test Review Ball Bounce 1.Draw the energy diagrams of on complete ball bounce. (4 diagrams) 2.The ball has a mass of 2kg and drops at 5 meters and bounces back up to 3 meters. A.Find the initial GPE and final GPE. B.Find the velocity before it hits the floor and as it leaves the floor. C.Find its efficiency.

Unit Test Review Thermal Energy How do you calculate the amount of heat that is transferred to water?

Unit Test Review Thermal Energy A pot of 500 g of water is placed on a gas stove and is heated from 15 o C to 50 o C. 1.How much energy is transferred to the water? 2.If 90,000 Joules of CPE is used to heat the water, how efficient is the gas stove?
