Remember to review the packets and homework, your class notes, and the past quizzes.

Here is an excellent site that you can also use for review:
http://www.physicsclassroom.com/Class/

Remember the class notes are posted here:
https://sites.google.com/site/dandradeedusite/Home/physics-class-files


You should start reviewing now so that you have time to ask questions and absorb the material again.

IMPORTANT - You need to have your own calculator. A scientific calculator is all that you need. They only cost between $8 and $15. Target and Walmart have the best prices. I will not be providing calculators after midterms.

IMPORTANT - tell your parents that the progress reports are almost 3 weeks out of date and that they should check PowerSchool for an updated grade.

Egg Drop Calculations
Given/known info: mass (measured), height = 4m, time (measured)
convert mass from grams to kg.
Use conservation of energy to calculate the final velocity (PE1 = KE2)
Use Impulse Momentum theorem to calculate the impact force.


Calculations, along with a short description of your device and why you made it that way, are due the day of the quiz.

Thursday, 12/22
QUIZ - Periods 1, 3, 4, 6
on Work, Power, Energy and Momentum (Packets 4 and 5  )
Review the packets, class notes, and the worksheet from last Monday (sub work). You have the solutions to this so you should try the problems again on your own and then see if you did them correctly.

You can go here for more help too:
http://www.physicsclassroom.com/Class/momentum/
http://www.physicsclassroom.com/Class/energy/

You will get the main equations on quiz or on the board. You must be able to do the algebra and solve for different variables though.

You should start reviewing for it now so that you can ask questions on Tuesday or Wednesday.

Egg Drop Project

Physics

The Great Egg Drop

Your Challenge:

Build a device/vehicle that will protect a passenger (The Egg) from harm during a "crash".

The Rules:

• One raw egg (large or extra large) is to be used. YOU  supply the egg on the day of testing.

• No foreign substance(s) may be applied to the eggshell, especially for the purpose of increasing the strength of the shell.  Nothing may be permanently attached to the shell (i.e. rubber bands or glue).

• Glue may not be molded to form a “pod” or capsule around the egg or put on egg.

• The vehicle may be any shape or size.

• Vehicle MUST free-fall to the ground.  (No 'parachute' device or “wing” may be employed).

• Vehicle shall be designed to withstand a fall from a minimum height of two meters.

• Final drop will be 4 meters.

• Egg shell integrity must be able to be proven to be uncompromised after impact;

The egg must be able to be easily removed in order to prove this.

• Examples of materials that may be used for construction: (you can use other materials)

Toothpicks (wooden only) no limit

Soda straws (any type) 5 straws or 50 cm total length

Paper (standard notebook type) two (2) sheets; may NOT be wadded

Glue (any type) Glue sticks may not be used for structure

NO PILLOWS, BUBBLE WRAP, SHOES, OR BOXES MAY BE USED.
Additional extra credit points may be earned in the following categories:

• Aesthetic design (does it look nice)
• Most spectacular crash

In addition, you must calculate the object’s velocity at impact and its change in momentum using the conservation of energy formula. You will also be timing the fall and then calculating the Impulse and Force at impact.

Schedule:

Day 1 - research and initial design

Day 2 - assembly and test drop

Day 3 - redesign and modification and final drop

Calculations:

Group members: _________________________________________________________________

Class period: ______

Egg Drop Calculations

m_egg = 60grams

mass: ____ g -- ________ kg              h = 4m                  t = ____

(what mass are you using for your calculations…)

PE = mgh =

PE­_­1 = KE₂     solve for v₂

p = mv         I = Δp                   I = F t     solve for F

Use h and t to find v₂ also as a check.

Description of design & why you chose this (why did you think this would protect the egg?)

Roller Coaster Project

Roller Coaster Physics Online Project 

Objective: to apply the concepts of forces, Newton's laws, Work, Power and Conservation of Energy and Momentum to the design and analysis of Roller Coasters. 

1. Go to http://library.thinkquest.org/2745/data/ke.htm and read about the energy conversion in a roller coaster. Take notes so that you can better design your roller coaster.

2. Go to http://www.learner.org/interactives/parkphysics/coaster.html and read the first page. Then click on "How did coasters come to be? Read more about their history" and read about roller coaster history. Then click on "Back to Roller Coaster" which will bring you back to the start. Click on "Design a Roller Coaster" and follow the instructions. Make sure you click on the "safety inspection" after you are done with the design. Try out more than one design also. Take notes on what you learn and do. 

Using the height of each hill you select, calculate the PE at the top of the hill. Use this to calculate the KE and Velocity at the bottom of the hill. Assume a mass of 1000kg for the roller coaster car and occupants. 

3. Go to http://www.funderstanding.com/coaster and use the simulation to try out different roller coaster designs. Change the height of the initial hill, loop, and second hill. Start a new track and design your own layout. Watch what happens depending on what you do with the design.

Using the velocity shown on the simulation, calculate the KE of the car at the bottom of track. The mass slider is 100 - 1000 kg. Then, calculate the height of the first hill using the conservation of energy. 

Change the initial hill height, mass, and loops and second hill height and repeat analysis. Write down your observations of what happened as you changed each variable. Remember to only change one variable at a time. 

All notes and calculations will be turned in for a grade. I will also be checking to see how your designs work as you are working. 

If you have time:

4. Go to http://kids.discovery.com/games/build-play/build-a-coaster and try out the roller coaster game. See how well you do.

5. Go to http://tlc.howstuffworks.com/family/roller-coaster.htm and read all about Roller Coasters.

Schedule Update for Physics

This week we did the Work, Power, Energy lab, an online lesson, and then started Roller Coaster Physics.

If you were absent for any of these things, make sure you see me for your make up work.

Next week we will:

• review Work, Power, Energy and Momentum problems
• do the Roller Coaster Physics project
• start the Egg Drop project

Work and Power notes

Tuesday (per 1) and Wednesday (per 3,4,6) we did Work and Power. We did #1-4 from the Packet in class and went over them in class.

Slides for the lecture are here:

Solution to challenge problem from the other day

The other day I put a challenge problem on the board.

You had a box on a 30 degree incline that started at v0=0 and then reached v=8m/s after t=2 sec. You had to find the coefficient of friction.

Here is the solution. Notice how I did not plug any numbers in until the last minute and that the mass cancelled out.

Cool electronic pen I talked about in class

I'm sharing this information with students about the Livescribe Pen today and Friday. The Livescribe pen records everything you write and can also record audio. It's a great tool, especially in college, to take notes in class. Your notes and audio recordings are then saved to you computer.

They are not cheap ($80-$190, depending on memory ) but there are sales and discounts available sometimes and it could be a good investment.

Here's some more info on it:  http://goo.gl/v3Wer
