What is the gravitational constant?
The gravitational constant is the proportionality constant that is used in Newton’s Law of Gravitation. The force of attraction between any two unit masses separated by a unit distance is called the universal gravitational constant denoted by G measured in Nm2/kg2.
What is Newton’s universal law of gravitation?
Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with force directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
Is the value of g the same everywhere on earth?
No, the value of g is different at different places on the surface of the earth. The acceleration due to gravity is smaller at the equator than at the poles. This is because g is inversely proportional to the radius and the radius of the earth is smaller at the poles and larger at the equator.
What is the value of the gravitational constant G on the moon?
The value of the gravitational constant at any part of the universe remains constant which is 6.67408 × 10-11 N m2 kg-2.
