Gravity is a natural phenomenon by which all objects with mass are brought toward each other. It is a force that is responsible for keeping planets in orbit around the sun and for keeping objects on Earth from floating away into space.
Sir Isaac Newton is credited with discovering the concept of gravity in the late 17th century. He developed the theory of universal gravitation which states that every object in the universe attracts every other object with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them.
Newton's theory of gravity explains why objects are attracted to each other while Kepler's laws of planetary motion describe how planets move around the sun. Newton's theory is based on the concept of gravitational force, while Kepler's laws are based on observations and mathematical calculations.
Yes, mass has a direct impact on the strength of gravity. The greater the mass of an object, the stronger its gravitational pull. This is why larger objects, such as planets, have a stronger gravitational force than smaller objects like asteroids.
As of now, there is no known way to manipulate gravity. However, scientists are continuing to research and study the concept of gravity and its effects, which may lead to new discoveries and technologies in the future.
