Uniform Motion Lab

Controlled variables 1. The lighting was kept constant during the complete test. No additional light sources were added throughout the experiment, nor were some(prenominal) light sources removed throughout the experiment. This minimized the errors involved with toilsome to read and record the indicated measurements on the ticker mag tape, as well as the ability to analyze the experiment. 2. The kindred person measured and recorded the height and length of the twist plane and level horizontal report to ensure consistency in the transcription of data.By having the alike(p) person read all of the measurements minimized the level of uncertainty in position and angle of class period values. 3. The same person recorded all measurement values on the ticker tape to ensure consistency in the recording of data. By having the same person read all of the measurements minimized the degree of uncertainty in position and angle of reading values. 4. The propel timer was set to a frequency of 10Hz (10 dots/s).This eliminated the possible random error that could have been associated with the recording of time if a person were to record the time, due to delays in reaction time. By having the consistency of the spark timer record the time values the total accuracy and precision for the experiment was increased. 5. There was no wind or abnormal air movements during the complete test. No doors were opened or closed during the experiment, nor were any windows opened or closed, ensuring that the results would not be affected from air currents pushing or angling the car.Procedure 1. victimisation a meter stick, one person measure and record the height of incline plane at its highest point from the table. Then, using a meter stick, one person measure and record the length of the incline plane and the level horizontal track. 2. Without the use of ticker tape or a spark timer, office staff the car at the top of the incline plane. Release the car. Use this as a trial hang on to ensure the ramp will produce efficient results. 3. Attach one end of the ticker tape onto the top of the car with the use of masking tape. 4. Turn on the spark timer.
