1. Physics 11 Advanced Mr. Jean April 23 rd, 2012

2. The plan: Video clip of the day Return Quiz Review Quiz Check homework problems Conservation of energy Work, PE & KE. Kinetic Energy Review sheet

3. Return Quiz

4. Review Test:

5. Questions to check: P. 250 –#28 & 29 P. 254 –#30 & 34

6. Conservation of Energy: E k1 + E p1 + E e1 = E k2 + E p2 + E e2 E k1 = kinetic energy before event (J) E p1 = gravitational potential energy before event (J) E e1 = elastic potential energy before event. (J) E k2 = kinetic energy after event (J) E p2 = gravitational potential energy after event (J) E e2 = elastic potential energy after event. (J)

7. Roller Coaster Awesomeness: Welcome to the Lawyer Proof Pain-0-rama 2000 Theme Park. The star attraction of this theme park is a roller coaster which has an abrupt end. Calculate the potential energy, kinetic energy and velocity at the various locations.

9. 1) E p = E Total 2) E Total = E k + E p

11. Kinetic Energy Review Sheet: This sheet should be review at this point. Solutions for this sheet will be available on Wednesday and my expectation is you complete it for then.

12. To do: Complete Questions on Kinetic Energy worksheet for Wednesday. (Start now!) Upcoming items –Spring Lab Spring Constant, Restoring Force & Hook's Law Pendulum Motion
