Here's why:
* Universal Law of Gravitation: Newton's law of universal gravitation states that every particle in the Universe attracts every other particle with a force that is:
* Proportional to the product of their masses: The more massive the objects, the stronger the gravitational pull.
* Inversely proportional to the square of the distance between their centers: The farther apart the objects are, the weaker the gravitational force.
Formula:
The force of gravity (F) between two objects can be calculated using the following formula:
F = G * (m1 * m2) / r²
Where:
* F = force of gravity
* G = gravitational constant (approximately 6.674 × 10⁻¹¹ N⋅m²/kg²)
* m1 = mass of the first object
* m2 = mass of the second object
* r = distance between the centers of the two objects
Example:
The Earth pulls on the Moon due to gravity. This gravitational force keeps the Moon in orbit around the Earth.
