September 10th (Monday) Review Great Race & do GOM1 Hmwk
If you were gone today:
You do not need to make up the Giant Slide quickie lab if you caught the day after when we demonstrated the factors that affect whether an object will win/lose a race down an incline. Mr. Konichek did not collect this lab but if you still wish to experience it, you can find the materials behind the classroom. Just bring up someone who has done it and experience being a scientist yourself.
Grade GOM1 1-5 from our smartboard answers below (done in class together).
Note the data we collected on the walk, jog, sprint and how we graphed that data in tomorrows class webpage..

Giant slide
Get out your lab notes from last and predict which object will win.
Distance-Time Graphs (Will need to do the following for Physics 500 tomorrow)
Volunteer three students to walk, jog, and sprint 15 meter of the long hallway outside the classroom. Have another row record times at 3,6,9,12, and 15 meters with the sixth student in the row collect the data from the timers before the next trial. Make a data table and graph the data in excel. We will do this part tomorrow.
Grading Homework 1-5 Graphs of Motion I:
Completed GOM1 1-5 smartboard answers worked out in class.
Period 1 Period 2 Period 3 Period 4 Period 7 Period 8
Big Pictures for today:
1. Factors that affected which object won/lose the Giant Slide brainstormed and demonstrated in class today included: 1). Weight/Mass/Density 2). Shape (a sphere would beat a ring) 3). Texture/friction (stickyness)
4). Radius 5). Length of incline race 6). Inside mass beats outside mass with same radius disk 7). The full pop can always won as the liquid state rolled faster than solid state (an eyeball in water was 2nd fastest) just eyeballing the race (ha, ha). 8). An outside mass rolling uphill first would be slow but the same disk with the outside mass on the downhill side of the roll would win so roller could control which one would win.
2. In GOM1 homework 1-5 you learned:
1). That when you convert from one unit to another you are actually multiplying by the number 1. For instance 60 seconds = 1 minute so both 60 sec/ 1 min = 1 and so does 1 min/60 sec =1 but only one of the two will cancel out the old unit and introduce the unit you are switching to. Thus 9 min times 60 sec/ 1 min = 540 sec.
2). That one uses v = distance/time to calculate speed or velocity.
3). That given velocity and either distance or time you can solve the variable not given by kind of cross-multiplying meaning that to solve for a variable in a proportion just keep variable diagonal with each other diagonal with each other or together. Example: If abc/d = ef/ghmn then note abcghmn are diagonal from each other and def are also diagonal from each other so if you wanted to solve for m lets say m = def/abcghn so that the same variables are still diagonal from each other or together.
4). That in a distance/time graph, time cannot go backwards so no / shape possible.
5). Thanks to Mrs. Steel, Mr. Konichek can now place a PDF formatted file on the smart board, write on it, and save what was written to you can see it on this webpage. Thanks, Mrs. Steel! Teamwork within SPASH works well....
