Pd. 9 Interpreting Slope and Intercept

HW:

• The equation for the speed of a ball that is thrown straight up in the air is given by v = 128 – 32t, where v is the velocity (in feet per second) and t is the number of seconds after the ball is thrown. With what initial velocity was the ball thrown? What is the meaning of the slope?  What are the units of the slope?

Easy As Pie

Objective:
The student will measure circumference and diameter with appropriate accuracy and precision. The student will graph circumference vs. diameter, determine the slope, and identify the physical significance of the slope and calculate the % error.   Students will suggest ways to increase the precision of the lab.

• (Your groups and physicist were assigned in class)

• Create a  Poster of Fundamental Units for your Group each person should be responsible for one unit
• 7 Fundamental Units-. things that can be measure that do not depend on other quantities
• Based on your observations
• Mass is fundamental
• density is not fundamental it has mass and volume
• volume depends on distance ^3 or (LxWxH)
• therefore volume can not be fundamental

• Use Scientific Method to Create and determine rules for the following ( You may work with your adopt a physicist Group) The process is identical to "Petals Around A Rose"
• You may not look up the rules you must  use the answers from the WS to determine them
• State which questions help you prove your rule
• If your rule works for all examples stop if not continue to test and refine your hypothesis
