Simulations with Pressure and Temperature

Today we'll be looking at a simulation that varies temperature and heat.
This will be used in conjunction with the handout given to you today. Please click on the link below to start the first simulation:

Winter Break Packet

Hey Folks,
I've attached the winter break packet on this post. Download it below if you need it.

One correction, on the momentum packet:

1. For problem 1: mass of both balls is 10 grams
2. For problem 2: mass of yellow ball is 15 grams and mass of blue ball is 15 grams.
   
3. For problem 3: mass of yellow ball is 15 grams and the blue ball is 10 grams.
   

You need that info to work out the problems.

For the reading part, don't worry about the "One Step Calculation" questions as I forgot to give you the questions for them!

So, all in all you need to finish:

1. Momentum handout (attached right here for you to download. Open this with Word or some other text editing document) Momentum_Collision_Problems.doc
2. Mass and weight reading and questions.
   
3. Read section on Mechanical, Potential, and Kinetic Energy. Questions given to you upon return.

Good luck!
Rodrigo

Monday and Thursday 11/30 and 12/3

Welcome back from Thanksgiving!
Monday we had no warm up, and went straight to working on the handouts "Material Properties" and "Average Speed +Graphs Handout".

I also handed out hints to the physics packet on a half sheet of paper.

We also did the following things in class.

§ Showed students exemplar car, explain they will have 3 types of balsa sticks to use.

§ go over how to crush sticks.

§ Show video of car rolling down. Use frames to find time. Go over average speed graphs.

On Thursday we finished the Average Speed graphs and "Material Properties" handout and turned in our binders to be graded. There was a prelude for Thursday.

Monday 11/16

Prelude: Free body diagram

Objective: a force requires a change in velocity or acceleration.

Notes on work:

Work= force* distance

Work is the change in energy of something.

Work = change in kinetic energy.

Kinetic energy: Energy of motion. Equation = 1/2mv²

Potential energy: energy of position

PE = mgh

Potential energy: a bow, an object elevated. Something that has a force acting on it but no work.

Introduce lab. Students will drop balls first and then measure the mass of their ball. 3 balls per group if possible. Two timers per group if possible.

HW: Blue handout: page 32 and 37.

Monday 11/9

1. Today's prelude: finish momentum problem set.
   
2. Today we got a handout on Momentum Lab. Make sure you finish problems 1 and 4.
   
3. Finish all of momentum problem set for homework.
   

Wednesday 11/4

1. Students worked on conservation of momentum problem set from the textbook. This is a handout and the problems are listed on the handout.
   
2. We also took notes on conservation of momentum. See another student to get these notes and make sure you list them on your table of contents!
   

Monday 11/2

1. Prelude 1/2 sheet:
2. Notes on Free Body Diagrams
3. White handout: drawing free body diagrams
4. Homework: more practice on drawing free body diagrams using Newtons 3rd Law.
