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.
