Tactile graphics

The acceleration values shown in Figure 7 are plotted in the image that is contained in the file named Phy1080b1.svg, along with theheight values and the velocity values.

Analysis of the results

The main difference between Figure 7 and Figure 6 is the addition of an acceleration column on the right in Figure 7 . (In addition, I abbreviated feet and seconds as ft and sec, and reduced the space between columns tomake it all fit in the available space.)

Except for the first two values at the top of the acceleration column, every acceleration value is -32.2 ft/(sec*sec). This is what we predicted earlier whenwe observed that the velocity curve is a straight line with a constant negative slope. (Note that the procedure used to estimate the acceleration did not allow for anaccurate estimate of acceleration for the first two values in the acceleration column.)

Free fall

According to Wikipedia , free fall is any motion of a body where gravity is the only force acting upon it.
