![]() That the speed increased, remained constant and then dropped to zero Using our adjusted velocity values, we produced a new graph which showed.When we graphed the velocity, the graph showed that speed increased, reachedĪ constant value for a few seconds, then increased and kept increasingĮven when the elevator stopped.Rest to 0.66 m/s 2, then did not accelerate until it reached a peak acceleration of 0.74 m/s 2. time graph shows that the elevator decelerated from In this experiment we started collecting the data on the 2nd floor as the elevator travelled up to a stop at the 4th floor. It collected the elevator's acceleration at 0.1 second intervals for a total of 20 seconds. In this experiment we rode the elevator at Midwood High School, but instead of going down, we decided to go up.We zeroed the accelerometer and let the Logger Pro software collect the acceleration of the elevator. time graph shows that the elevator started from rest and accelerated in the downward position a distance ofġ4.309 m, the distance from the 3rd floor to the basement of Midwood ![]() We again applied the integral function to the velocity graph to graph the displcement vs.When we reached the basement the graph shows that the elevator decelerated and came to Speed of 0.820 m/s at 6.1 s, until it reached a constant velocity. time graph shows that the elevator started from rest and accelerated in the downward position reaching a peak We applied the integral function to the acceleration graph to graph the velocity vs.time graph shows that the peak acceleration of 0.64 m/s 2 was reached at 1.9 s, dropped to 0 m/s 2 while the elevator was traveling at a constant speed, and decelerated to 0.71 m/s 2 at 18.9 s until the elevator came to a rest. In this experiment we started collecting the data on the 3rd floor as the elevator travelled down to a stop in the basement. In this experiment we rode the elevator at Midwood High School and using an accelerometer that was connected to the laptop through the LabPro.We zeroed the accelerometer and let the Logger Pro software collect the acceleration of the elevator. An accelerometer is an instrument used to measure acceleration and the effects due to gravity. One common unit of acceleration is known as g, the acceleration due to gravity of the Earth. ![]() It is measured in SI units by meter/second 2. Acceleration is defined as the rate of change of velocity with respect to time.
