How Does ‘Gravity’ Affect the Movement of Planets?

Gravity is like a giant invisible string that pulls planets toward the sun. When a planet moves fast enough, it doesn’t fall into the sun, it keeps going around and around, just like when you swing on a rope.

Why It Works

Imagine you're holding a ball on a string and spinning in circles. If you let go, the ball would fly off in a straight line. But gravity acts like that string: it tugs the planet toward the sun while the planet keeps moving forward, making it orbit instead of falling down.

Examples

  1. Gravity keeps Earth in orbit, just like a ball on a string stays in circular motion.
  2. If gravity disappeared, we’d float away into space, or fall straight into the sun!
  3. Planets move sideways as they’re pulled toward the sun, creating an orbital path.
