April 29, 2014Homework: Complete Motion Review sheet- Due Thursday- Review your notes on chapter one- **Open book Quick-quiz on Friday**

Do Now: •Write down homework•Open notebook and textbook to pg. 25

Math Practice Problems on pg. 25 in the textbook.

Kinetic Energy(KE) - the Energy due to Motion

What are two factors that affect kinetic energy?

-Mass- KE increases when the mass increases

-Velocity- KE increases when velocity increases

•Stored energy related to an object’s position or shape•Energy stored and used later

Elastic Potential Energy

What is an example of potential energy?

Gravitational potential Energy:• Related to an

objects height- equal to the work done to lift it- Weight x Height

Interpreting Diagrams: Does the red skier have more gravitational potential energy on the higher ski-jump or the lower one?- Why?

Type main kinds of Energy:--Kinetic Energy - Potential Energy

Energy is conserved—Can not be created or destroyed, only transferredfrom one type to another

Energy is Conserved-- TransferredEnergy transfers from Potential to kinetic energy once the object is in motion

Where are the areas of greatest -Potential Energy?-Kinetic energy?

-Why?

April 30, 2014Homework: Review Sheet Due tomorrow:Quick Quiz on Friday- Review Notes on chapter one and on Energy

Do Now: Write down Home-work-

Which letter shows where gravitational potential energy the greatest?

And where Kinetic Energy is the greatest?

What Ride from 6 Flags moves similar to this type of motion?

Where are the areas of greatest -Potential Energy?-Kinetic energy?

-Why?
