What is Newtonian gravity?

Newtonian gravity is like a super-strong invisible string that pulls things together when they’re near each other.

Imagine you have two balls on a trampoline. When you drop one ball next to the other, the trampoline bends around it, and the second ball rolls toward the first one because of that bend. That’s kind of how gravity works: big objects like Earth or the Sun bend space around them, and smaller things like us or planets get pulled toward them.

Think about jumping on your bed. The more you weigh, the more you push it down, and the harder it pushes back up when you land. Gravity is like that stretchy floor: Earth pulls you down because it’s big and heavy, just like how your bed pushes back when you jump.

Newton said that everything with mass, like you, a rock, or even the Moon, pulls on everything else. The bigger something is, the stronger its pull. That’s why we stay on Earth instead of floating off into space, Earth’s gravity holds us in place, just like your bed holds you when you jump.

So gravity isn’t magic, it's a kind of invisible stretchy force, pulling things together based on how big and heavy they are.
