'Uniform Motion Lab\r'

'Controlled variables: 1. The settleing was kept constant during the complete test. No additional light sources were added throughout the sample, nor were each light sources withdraw throughout the experiment. This minimized the wrongful conducts involved with laborious to demand and participate the indicated measurements on the inwardness read, as well as the mightiness to analyze the experiment. 2. The same person metrical and video put downed the height and length of the flip plane and direct horizontal lighter advance to ensure consistency in the arranging of data.By having the same person read entirely of the measurements minimized the degree of distrust in position and angle of version value. 3. The same person recorded all measuring values on the ticker immortalize to ensure consistency in the transcription 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 spark 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. Using a step stick, one person measure and record the height of course 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, manoeuver the car at the top of the incline plane. Release the car. Use this as a trial run to ensure the incline will produce efficient results. 3. connect one end of the ticker tape onto the top of the car with the use of showing tape. 4. Turn on the spark timer.\r\n'
