Hey there! This is the place to post any comments, questions, or additions to MST homework! Mr. Jansma's site: []

Does anyone know when the tower experiment graphs and stuff are due? - Ajay

thursday April 5, 2012

Things to include in the gravity assignment:
 * 1) Table for Gravity 1 (height of playdoh, test 1-3, average, error, actual height of center of mass (AHCM))
 * 2) Table for Gravity 2 (height of ruler, test 1-3, average, error)
 * 3) Sample calculation for standard deviation
 * 4) Sample calculation for AHCM
 * 5) Graph for Gravity 1 (Height of Mass vs. Tilt Angle)
 * 6) Graph for Gravity 1 (AHCM vs. Tilt Angle)
 * 7) Graph for Gravity 2 (Height of Ruler vs. Shifted Length)
 * 8) One paragraph about R2 (R squared) value of the two Gravity 1 graphs
 * 9) One paragraph answer to Gravity 1 reflection "In words and diagrams, explain the relationship between the height of center of gravity and the stability of the structure."
 * 10) One paragraph answer to Gravity 2 reflection "In words and diagrams, explain the relationship between the height of center of gravity and the stability of the structure. Why is the roll able to stand even though it has a ruler in it? Why does the tube fall over when the ruler is moved right or left of center?"

Where did you get this??? - Anya Mr. Jansma told the whole class, and he ain't telling us again. I don't know if you have the reflection questions written down, so I posted this. - Daniel Liang (Apr. 4, 2012 8:56 PM) Yeah it was just the reflection i was wondering aboout. - Anya

Write down the 3 ways to find the center of mass on the penny plate (in more detail than this)! I contribute so much! - Daniel Liang (Apr. 13, 2012 6:24PM)
 * 1) Try balancing it at different points
 * 2) Using the formula of x and y of center of mass
 * 3) Using the string and weight (I forgot what it was called) with skewer method.
