* Mass: The more massive an object is, the stronger its gravitational pull. Think of it like this: a planet has a stronger gravitational pull than a rock because it has a lot more mass.
* Distance: Gravity weakens rapidly as the distance between objects increases. This is why you feel the Earth's pull strongly when standing on its surface, but you don't feel it as much when you're in an airplane or a space station.
This relationship is captured in Newton's Law of Universal Gravitation:
* F = G * (m1 * m2) / r^2
Where:
* F = Force of gravity
* G = Gravitational constant (a fixed value)
* m1 and m2 = Masses of the two objects
* r = Distance between the centers of the two objects
Key Points:
* Direct Proportionality: Force of gravity is directly proportional to the product of the masses. This means if you double the mass of one object, the force of gravity doubles.
* Inverse Square Law: The force of gravity is inversely proportional to the square of the distance between the objects. This means if you double the distance, the force of gravity is reduced to one-fourth of its original value.
