I am taking the height of the basketball hoop as being 3.053m. I am taking the height of the basketball player to be 1.984m. My own height is 1.6m. This diagram of a basketball court has been taken from http://en.wikipedia.org/wiki/Basketball. In order to model the basketball as a particle I have made the following assumptions: * That there is no air resistance. I have made this assumption because the effect of air resistance on the speed of the basketball would make it extremely difficult to model. * That gravity is 9.8ms-2. I have made this assumption because the strength of gravity on earth is <blah.blah> and I have taken this as being 9.8 as 2 significant figures is sufficient for accuracy.

and PET (positron emission topography). Converging evidence strongly implicates area MT (V5) as being important in motion perception. In recent years we have also come to appreciate that MT provides substantial input to other 'satellite' areas, particularly the medial superior temporal (MST) area where local motion signals are combined by neurons that respond to optic flow (Badcock & Khuu 2001). These areas also have an important role in motion perception. The parietal pathway The study of the visual striate cortex and extra- striate cortex led to the notion of specialization.

The CBL unit was then attached to a Ti-83 plus calculator to gather the data from the experiments. The HIKER program on the calculator was performed, which took distance measurements every 0.1 seconds for 6 seconds. Each test was collected then the results were inputted into the Graphical Analysis program for regression analysis. The first test was that of a person walking away as shown in figure 1. The second test was that of a person walking away at a faster pace as shown in figure 2. The third test was that of a person walking towards the detector as shown in figure 3.

The change in position from moment to moment is expressed as a velocity (meters per second). The change in velocity from moment to moment is expressed as an acceleration (meters per second per second). The position of an object at a particular time can be plotted on a graph. You can also graph the velocity and acceleration of the object versus time. A graph is a mathematical picture of the motion of an object. For this reason, it is important to understand how to interpret a graph of position, velocity, or acceleration versus time. In this activity you will plot a graph in real-time, that is, as the motion is happening.
