Here's a breakdown:
* Gravity: A fundamental force of nature that attracts any two objects with mass.
* Mass: A measure of the amount of matter in an object.
* How it works: The more massive an object, the stronger its gravitational pull. The closer two objects are, the stronger the gravitational force between them.
Newton's Law of Universal Gravitation describes this force mathematically:
* F = G * (m1 * m2) / r²
Where:
* F is the force of gravity
* G is the gravitational constant (a very small number)
* m1 and m2 are the masses of the two objects
* r is the distance between the centers of the two objects
This means:
* Gravity is directly proportional to the product of the masses.
* Gravity is inversely proportional to the square of the distance between the objects.
Examples:
* The Earth's gravity pulls you towards its surface.
* The Sun's gravity holds the Earth and other planets in orbit.
* The Moon's gravity causes tides on Earth.
