Imagine you have a giant tunnel going straight through the Earth, from one side to the other. If you jumped in, gravity would pull you down toward the middle, and then you’d zoom back up on the other side like a pendulum, kind of like bouncing on a trampoline. You’d keep swinging back and forth unless there was air or friction to slow you down.
Examples
- You jump into a hole through Earth like it’s a giant slide.
- You float up to the other side before falling back down again.
- You keep bouncing between two sides without stopping.
