Understanding Energy and Momentum Through Fun Experiments

Learning about energy and momentum can be a lot of fun! Here are some simple experiments you can try to see these ideas in action:

1. Pendulum Experiment:

   • When a pendulum swings, it moves up and down.
   • At its highest point, it has a lot of potential energy because it's up high.
   • As it comes down, that potential energy turns into kinetic energy, which is the energy of movement.
   • At the bottom, it has the most kinetic energy and the least potential energy.
   • This shows how energy is conserved, or kept safe, as the pendulum swings.

2. Collisions with Marbles:

   • When two marbles bump into each other, this is called a collision.
   • In a perfect scenario, the amount of momentum (the tiny push that makes objects move) stays the same before and after the bump.
   • You can think of momentum like a game where both marbles have to keep the score balanced.
   • By measuring how fast and heavy each marble is, you can see how their momentum changes but still stays equal.

3. Roller Coaster Simulation:

   • Imagine you are on a roller coaster.
   • As it goes up and down, you're watching how fast it goes at different spots.
   • At the top, it has potential energy because it’s high up.
   • As it zooms down, that energy changes into kinetic energy because of the speed.
   • Throughout the ride, the total energy stays the same, just changing between potential and kinetic.

These fun experiments help us understand some basic rules in physics. They show how energy and momentum work in the world around us!
