what is gravitational force? please answer.
Gravitational force is the universal force that act in between all the masses in the universe. Gravitational force surrounds us. It is what decides how much we weigh and how far a basketball will travel when thrown before it returns to the surface. The gravitational force on Earth is equal to the force the Earth exerts on you. At rest, on or near the surface of the Earth, the gravitational force equals your weight. On a different astronomical body like Venus or the Moon, the acceleration of gravity is different than on Earth, so if you were to stand on a scale, it would show you that you weigh a different amount than on Earth.
According to Newtons law of gravitation, every point mass attracts every single other point masses by a force (acting along the line joining their centres) which is proportional to the product of their masses and inversely proportional to the square of the distance between them.
mathematically we can write as,
