October 3 (Thursday) Factors of Acceleration Lab Day 1
Note: another take-home lab (Balloons & Bottles) next Monday so start getting in groups of 3 or 4 students from any one of the ten Physics classes this year again...
GNATS 1 on Multiplying is due Oct. 18th
BIG PICTURE OF GRAPHING CONT.
Just like a picture is worth a thousand words, a graph of data beats looking at a data table of numbers hands-down.
You learned that a graph can be designed so the slope tells you additional information. Examples: Slope of distance/time graph gives you instantaneous speed and the slope of a speed/time graph instantaneous acceleration. (Note: The derivative in Calculus gives you slope. The first derivation of a distance/time function gives you speed and the second derivative acceleration.)
You also learned that a graph can be designed so that the Area under the Curve tells you additional information.
Examples: The area under a speed/time graph gives you distance traveled and the area under an acceleration/time graph the speed. (Note: In Calculus, when you integrate a function, you calculate the area under the curve.) (Also note: If you differentiate the formula of the volume of a sphere you get the formula for the surface area of a sphere and if you integrate the formula for the surface area of a sphere you get the formula for the volume of a sphere.)
This unit you'll learn that the shape of a graph can give away a formula that fits the data. The three we use in this years Physics class the most are varies directly (a straight line), varies inversely (the y = 1/x curve) and varies directly as the square (the y = x squared) graph.
In the Factors That Affect Acceleration Lab you are to determine from the acceleration/force in washers and acceleration/addition mass graphs which of the three above functions each graph fits and put them together into one relationship. Note these smart board graphs drawn today of the three relationships.

Factors That Affect Acceleration Lab
As a class we collected data today for the Factors That Affect Acceleration Lab. Tomorrow we will have all period to continue explaining the lab and to work on it in groups of two. If gone today, watch the video of students collecting data (when I get around to getting it off the camera), download the excel file from the Q:drive at school under 13-14 Physics Hagstrom, Wernicke, Konichek then Factors that Affect Acceleration Lab and Acceleration Lab Start for everyone to save class time. Note tomorrow for more information to complete the lab.
Period 1 Data Collected Period 3 Data Collected Period 7 Data Collected
We will continue the lab tomorrow for the shorten period schedule.
