Question
In a spring of air lab, we are asked to drop a marble into a tube filled with air that is connected to a bottle filled with air. We are determining the value of the bulk modulus by observing the movement of the marble. Measurements are taken from the use of two methods: static and dynamic. In the static method, the marble is simply dropped into the tube and then measurements are taken of how far down the tube it dropped. In the dynamic method, we measure periods; that is we measure the bouncing motion of the marble in the tube as it is dropped and then moves up and down due to the air pressure. What types of systematic/random error may arise in this experiment?
Explanation / Answer
Improper measuring equipment and improper measurement technique re the factors that may result in systematic errors.
Changes in the environment where the measurement is being done and unpredictable reasons that may result in random errors.
