Minute Physics: What is Gravity?

Gravity is the invisible force that keeps us on the ground and makes things fall when we drop them.

Imagine you have a big, heavy ball, like a basketball, and a small, light ball, like a ping pong ball. If you let both go at the same time from the top of a slide, they will both roll down, but the heavy one might be faster. That’s because gravity pulls harder on heavier things.

Think of Earth as a giant magnet that pulls everything toward its center, like when you drop your favorite toy and it falls to the floor. This pull is called gravity, and it's why we stay on the ground instead of floating off into space.

Even though gravity is invisible, we can feel it every day, when we jump, when we walk, or even when we sit still. It’s like a gentle hand that never lets go.

The same force that keeps you on Earth also keeps the moon circling around our planet and makes the planets orbit the sun. So gravity is not just something that happens on Earth, it's everywhere in space too!
