What is Gravity

The video explains gravity as a long-range attractive force between objects with mass, keeping us grounded and celestial bodies in orbit. It highlights Newton's discovery that gravitational force decreases with distance and is proportional to mass. The video also clarifies that gravity affects not just mass but energy, bending light and trapping it in black holes.
