Pendulums are great examples of how energy works, but they can be affected by some difficulties.
Energy Changes: A pendulum uses potential energy when it's at the top of its swing. This energy turns into kinetic energy when it swings down to its lowest point. This is how energy conservation works. But in real life, pendulums lose energy because of friction and air resistance. This makes it hard to predict how they will behave perfectly.
Friction: When the pendulum swings, friction at the hinge (where it’s attached) takes away some energy. This energy turns into heat instead of helping the pendulum swing back fully.
Air Resistance: The pendulum also has to push against the air as it swings, which slows it down and makes it take longer to stop.
To help with these problems, you could:
Even though pendulums have these challenges, if we work on reducing the energy losses, we can better understand and teach how energy conservation works with real-life pendulum examples.
