In this experiment, the main thing we have to have is a flashlight and Labview, the program. What we have to do was connect the flashlight with the wires that are on the NXT machine. After everything is prepared, the true experiment will start.
In this experiment, we will be testing it 4 times, and each time the shake time will either increase or decrease. In Labview, each test will take 30 seconds to record and get the result. For our first shake, the professor requested to start it slow first. So in 30 seconds, we recorded 32 shakes, and the results that appeared has showed that in 32 shakes, we create 12 voltage. After done recording the first trial, we did the second one. In the second trial, we start increasing the speed, and it end up of having 35 shakes in 30 seconds. In this trial, we created 77 voltage. Keep on going, we recorded 46 shakes in the third trial, and has created 89 voltage. In the fourth trial, we are increasing the speed more, and it end up of having 98 shakes. Surprisingly, the voltage that we created in this trial is lower than the previous one, which is 80.
In conclusion, I believe this experiment has told us that the faster and stronger you shake, the more voltage that you will create because when you shake up and down, the magnet inside the flashlight will move up and down as well. Therefore, the flashlight will create more voltage when you shake more. However, if your shakes only have speed and not power, the voltage that is create will not as being as much, for instance the fourth trial comparing with the third trial.
(Below is the chart of the number of shakes vs the voltage.)
