: Although it gets weaker with distance, gravity technically never drops to zero, meaning it influences the motion of stars and galaxies across vast stretches of space.
: Every object with mass in the universe attracts every other object, no matter how far apart they are. Gravitational Forces
: The strength of the force decreases rapidly as the distance between objects increases. If you double the distance, the force becomes four times weaker. : Although it gets weaker with distance, gravity
: The more mass an object has, the stronger its gravitational pull. This is why you feel the Earth's gravity but not the pull of a nearby building. If you double the distance, the force becomes
According to , this force is defined by several key characteristics:
The of gravitational forces is that they are always attractive ; unlike electromagnetic forces, which can both pull and push, gravity only pulls objects together. Licensed by Google
