What is gravity?
Gravity is a fundamental force of nature that exists between any two objects in the universe that have mass or energy.
It is the force that pulls objects towards each other, and is responsible for keeping planets in orbit around stars, moons around planets, and objects on Earth anchored to its surface.
The force of gravity is directly proportional to the masses of the objects involved and inversely proportional to the square of the distance between them. This means that the closer two objects are and the greater their mass, the stronger the force of gravity between them.
Gravity was first described mathematically by Sir Isaac Newton in the 17th century, and later expanded upon by Albert Einstein’s theory of general relativity in the 20th century. Gravity is a crucial component of our understanding of the universe, and plays a significant role in the behavior of celestial objects and the formation of galaxies.
