Data Analysis

As we investigate motion on inclined planes, we wanted to show the relationships in the data. Using graphs the students determined the patterns between the boards and the angle of the inclined plane. The students described the motion of the ball as a change in "speed." The ball was going faster as a result of angle. The change in speed was defined as "acceleration." In most cases the ball accelerated in a non-linear fashion. The students pointed out that as the inclined plane became steeper, the ball was accelerating less. Thus the graphs showed a curve.

Updates and Assignments
Next, the students are going to explore motion in more depth. Using the physics formulas for speed and acceleration, we will look at how moving objects behave.  The latest assignment sheet is available for download. Also, the textbook reading activity, F2 Chapter 2 was assigned and is due for Wednesday, 2/23/11. Assignments are available from the website.
