Lab-Aids: Energy Transfer - Motion of a Pendulum Kit
In this activity students investigate the motion of a pendulum and the energy transfers that take place as it swings. They first investigate how the physical characteristics of a pendulum affect the period of a pendulum. They are given several variables to test and then asked to design and carry out an experiment to test the effect of another variable of their own choosing. Once the data is collected, they analyze the cyclic transfer between kinetic and potential energy that occurs as a pendulum swings.
Scientific Concepts:
- Energy is a property of many substances and is transferred in many ways.
- Kinetic energy is energy of motion; potential energy is stored energy.
- The total energy of the universe is constant and although energy is transferred in many ways, it can not be destroyed.
