What Is Gravity?
A simple explanation of why objects fall and planets stay in orbit.
Gravity is the attraction associated with mass and energy. Near Earth, it makes unsupported objects accelerate toward the ground and keeps the Moon in orbit around Earth.
How it works
- Earth's mass contributes to its gravitational field.
- Objects near Earth are accelerated downward when unsupported.
- Orbital motion combines forward motion with gravitational attraction.
- Gravity acts over large distances.
Key takeaway: An orbit is not simply 'floating'; it is continuous motion shaped by gravity.
