Use a motion sensor to determine how the mass and length of a simple pendulum affect its period of oscillation.
This activity helps students determine how the mass and length of a simple pendulum affect its period of oscillation. Students determine:
- The period of a simple pendulum with variable mass but constant length.
- The period of a simple pendulum with variable length but constant mass.
- An experimental value for the acceleration due to gravity using a simple pendulum.
Students will gain experience conducting the following procedures:
- Measuring the position of a pendulum bob with respect to time.
- Identifying and measuring the period of oscillation for a simple pendulum from a graph of position versus time.
- Drawing a conclusion concerning the period of a simple pendulum as a function of the mass of the bob.
- Constructing a graph of pendulum arm length versus period and drawing conclusions about the relationship between the two variables.
- Constructing a graph of pendulum arm length versus the square of the period and drawing conclusions about the relationship between the two variables.
