Introduction

Acceleration is defined as the rate of change of velocity with respect to time. It is measured in SI units by meter/second2. One common unit of acceleration is known as g, the acceleration due to gravity of the Earth. An accelerometer is an instrument used to measure acceleration and the effects due to gravity.

Materials Used:

Experiment 1

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. It collected the elevator's acceleration at 0.1 second intervals for a total of 20 seconds. In this experiment we started collecting the data on the 3rd floor as the elevator travelled down to a stop in the basement. The results are compiled in this table.

Experiment 2

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. It collected the elevator's acceleration at 0.1 second intervals for a total of 20 seconds. In this experiment we started collecting the data on the 2nd floor as the elevator travelled up to a stop at the 4th floor. The results are compiled in this table.
