Saturday, December 22 through Wednesday, January 2 – No school – Winter break
Thursday, January 3
- DiscoveryRide movie and Q&A on trip
- Energy & its forms
- Energy is the ability for something to change itself or its environment
- Electrical, mechanical (acoustic, wave, etc.), thermal, nuclear, gravitational, chemical, electromagnetic, chemical, light, etc.
- Law of conservation of energy - energy cannot be created nor destroyed but it can be transformed
- Kinetic energy (use examples of kinetic energy from My Car's Safety paper)
- Potential energy: PE=mgh
- Work
- DiscoveryRide energy worksheet
Friday, January 4
- Finish DiscoveryRide energy worksheet
- Start Concept Development 8-1
Monday, January 7
- Gossamer Condor movie
- Intro. to Power Lab
Tuesday, January 8
- Power lab today
- This lab requires you to be physically active - you'll be running up a flight of stairs. If you cannot participate in the lab due to a physical condition then let Mr. Flint know.
- Power
- Power equals work divided by time (in watts [W])
- 1 Horsepower = 745 Watts
Wednesday, January 9
- P. 119, 2–8 due
- elim date 0809
Friday, January 11
- In class: Concept Development 8-1
- Bowling ball pendulum
- Extreme Machines: Pedal Power
Monday, January 14
- Energy and Work Problems due
- Go over problems in class
- Work is only done if the force is applied in the same direction as the direction of travel!
- If there is no distance then no work is done.
- How much work is done pushing a book down on a desk? none
- How much work is done sliding a book along a desk? W=Fd=frictional force times the distance. frictional force is equal to mu times the normal force
- How much work is done holding a book in a stationary position? none - no distance change
- How much work is done carrying a book up stairs? W=Fd=weight of the book times the height of the stairs. no work is done in the horizontal direction because no force is applied horizontally
- How can you do more work by carrying books up stairs? Move them a greater distance or move more books.
