Zara loved asking questions. She was the kind of kid who wanted to know why the sky was blue, why rain fell from the clouds, and why her little brother could never sit still. But most of all, she loved physics—the science of how things move!
One day, her teacher announced a Physics Challenge for the class: "Who can make something float in the air without touching it?"
Zara was thrilled! But how could she make something float? She tried using a fan, but the wind just blew things away. She tried balancing a marble on a spoon, but that wasn’t really "floating."
Then, she remembered something from a book about magnetism. "Magnets can push or pull without touching!" she thought.
Zara found two strong magnets at home. When she placed them close together, they repelled each other. Carefully, she balanced a small marble with a magnet inside over another magnet, and—it floated!
At school, Zara demonstrated her experiment. Her teacher smiled. "You’ve just shown us how magnetic levitation works! This is the same idea behind some high-speed trains!"
Zara beamed. Physics wasn’t just fun—it was magic in real life!
Exercises
- Gravity (Pulls things toward the Earth)
- Magnetism (Pushes or pulls without touching)
- Force (A push or pull that makes things move)
- Friction (Slows things down when they rub together)
