What is Gravity?

Gravity is the force that pulls objects towards each other. It is a fundamental concept in physics, discovered by Sir Isaac Newton. According to the law of universal gravitation, the force of gravity is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between their centers. This means that the larger the mass of an object, the stronger its gravitational pull. Gravity is what keeps the planets in orbit around the sun and the moon in orbit around the Earth. Understanding gravity is crucial to comprehending the motions of celestial bodies and the behavior of objects on Earth.
