The Big Push: data and assignment

Presenting the Data from the Car Push!
Here is your data analysis assignment.
•Using excel calculate the acceleration for each trial.
•Plot an appropriate graph of Force and Acceleration:
        Q: What does the trend line tell you? 
•The mass of my car  (con mio) is about 3000lbs (1400kg).
        Q: Is this consistent with the data?  If it is not, propose hypotheses explaining what went wrong.
                i.e.   What assumptions did we make that might be erroneous?
                        Where is the likely sources of error?
                         If you think we were pushing up hill can you calculate what angle would account  
                         for our discrepancies?  do it if you can.
•Friction/Resistive forces: Can you measure friction from our data? if you can try.
•What else can you make of our results?
•What should we have done differently?

Real Physics:  Rise to the occasion!

May the Forces be with You!

Short week this week due to Teacher Conferences.
Jump into this weeks Quest Assignment "Newtons Laws !" 
It is a pretty large assignment but it will get us into the unit. 
Plan on spending at least part of Wednesday going over the problems that are giving you trouble.

No school Thursday Friday.  Make plans to get together as study groups.

Don't forget about that Projectile motion lab.

End of Unit 2 (2-d motion)

Our unit 2 test will be next Wednesday, 10-22.   
     •Projectile Motion
     •Vectors
     •Circular Motion

Studying : For more practice problems look at the problems at the end of chapter 4 in your text.
Also, consider looking at the "useful link" : Physics tutorial listed here  at right.

Projectile Motion Labs:  
 Due 10-22.  Let's get these wrapped up.  See me if you are having problems.

Bowshot Data: David Anuta/MDP

If your data or videos did not work out - you may use these videos for data analysis.

test bowshot - wider angle shot
trial 1 about 45? 99yards
trial 2 Lower angle 85 yrds
trial 3 much steeper than 45- 75
trial 4 greater than 45 - 100yards
trial 5 less than 45 -103 yrds

Week of October 13 Circular Motion

Here is your to do list for this week:

1.   By Wednesday finish the Golf Problem introduced on Monday.
2.   Read for learning :  Sections 4.5-4.6 in your Text
3.   Continue to work on the Projectile motion lab and your 5 minute presentation.
4.  Launch into  the new Quest Assignment posted today.  "Circular Motion" 

Question:  When can you do your presentation?  sign up Wednesday 10-15

Vectors and Projectile Motion Week of Oct. 6

Projectile Motion Lab:

You self designed PML should be underway with data analysis and problem solving.
Remember, your goal is to conduct as complete analysis as possible for motion in 2D.
 Include:
 •Detailed tables containing all relevant data. 
•Graphs of  X vs. time,  Y vs. time and  trajectory graphs Y vs X. 
•Presentation of how you found and calculated the initial velocity and launch angle. 
•*If you can or if you are doing the "standard" approach you will need to present a graph of:
 Range (x) vs. sin2θ checking your datas approximation to the range equation.
Analysis:
•Using your data try to use it to answer some interesting questions (i.e. that are interesting to you)

We will discuss how your lab report will be included in class Wednesday, 10-8.

NEW QUEST ASSIGNMENT POSTED:  10-5   DUE 10-10
       "2d motion: more vectors and projectiles"
Work with me and with each other on solving these problems.  
Remember to work them in your notebooks with work clearly shown and organized.
You play as you practice.
