Main Idea Gravitational Force, defined in Newton's law of Universal Gravitation, is the attractive force between any two bodies of any mass, at any distance. Gravity is one of the essential forces that hold the Universe together. Newton's law of universal gravitation states that every object with mass in the universe is attracting every other object with mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance ... Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun. What else does gravity do? Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of ... Gravity refers specifically to the attractive force by which the Earth pulls objects towards its center. Gravitation is the general force of attraction between any two masses in the universe. Gravity is a fundamental force of nature that causes attraction between objects with mass. The strength of gravity varies on different celestial bodies, depending on mass and radius. Newton’s law of universal gravitation describes gravity as a force between two masses, decreasing with distance.
