Conservation of Energy Demonstration
Ever notice that a conventional roller coaster never goes higher than its first hill? Roller coasters always have to end lower than where they started because of a fundamental idea called the conservation of energy—energy is never created or destroyed, it only changes forms. Put another way, you’ll never end up with more energy than you start with.
In this project, you’re going to explore the conservation of energy. Rather than build a roller coaster, though, you’re going to use a simple pendulum as a stand-in. And, just to test your intuition, you’re even going to place the safety of your nose in the hands of physics!
Warning is hereby given that not all Project Ideas are appropriate for all individuals or in all circumstances. Implementation of any Science Project Idea should be undertaken only in appropriate settings and with appropriate parental or other supervision. Reading and following the safety precautions of all materials used in a project is the sole responsibility of each individual. For further information, consult your state's handbook of Science Safety.
