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?
