Name: Kevin Boles Lab Partners name: Brian Lord Lab Section: 5 Date of Experiment: 9-15-10 Understanding Motion Abstract: We all witness motion every second of every day; the wave of our hand, the passing of a car on the road, or even breathing. When something becomes so common to all things on the planet it is only natural for us to want to study and understand it completely. One of the methods is to use a sensor and a graph in order to see velocity and acceleration in an easier way, as we did in this particular experiment. We set up a sensor and a computer program that was able to track and graph the movement produced in front of the sensor. We would then attempt to match our movement to the preplaced graph on the computer. Upon completing three trials of each distance and time, velocity and time, and acceleration we found the perfect place to start your movement, which was 0.40m from the sensor. We also found the maximum speed we should reach in the second trial; this was 0.2m/s. Then last we found the acceleration of a free falling object, this acceleration was 9.5. Theory: When motion is witnessed and recorded it is integral to the process to know where it is in relation to a reference point, its acceleration, its direction, and how fast it is moving. These are the key parts to understanding the motion of any object, simple of complex. All of these aspects of motion can be plotted on a graph and from that graph you will be able to find where the best place to start movement is, how fast you should go, how long you should move, and also in what direction. All this and more we found from just moving in front of a sensor and plotting the graph of that specific movement. Many things can be learned from the three graphs that we produced. To explain the graphs further I will explain the different things that are plotted on the graph. The change in position of the object is the velocity. The change in the velocity is the objects acceleration. These two can also be graphed versus time so you can see the changes with respect to time. This experiment helps us to interpret the graphs of position, velocity, acceleration, and time while the motion is happening. Also, an object falls freely it accelerates because of the applied net force, that is gravity, and the differences of this being measured at several instances, can be used to determine acceleration due to gravity. The Laboratory procedure is broken up into three parts:
