Homework: 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

2. Math Practice Problems on pg. 25 in the textbook.

3. 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

4. Stored energy related to an object’s position or shape
Elastic Potential Energy
Stored energy related to an object’s position or shape
Energy stored and used later
What is an example of potential energy?

5. 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?

6. Type main kinds of Energy:
--Kinetic Energy
- Potential Energy
Energy is conserved—
Can not be created or destroyed, only transferred
from one type to another

7. Energy is Conserved-- Transferred
Energy transfers from Potential to kinetic energy once the object is in motion

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