The unit used to express the Universal Gravitational Constant is Newton. The Universal Gravitational Constant, denoted by the symbol G, is a fundamental constant in physics that appears in the law of universal gravitation equation developed by Sir Isaac Newton.
In the formula for the law of universal gravitation, the force of gravity between two objects is given by F = (G m1 m2) / r^2, where:
- F is the force of gravity between the two objects,
- G is the Universal Gravitational Constant,
- m1 and m2 are the masses of the two objects, and
- r is the distance between the centers of the two objects.
Therefore, the unit for the Universal Gravitational Constant, G, is Newton, named after Sir Isaac Newton, who formulated the law of universal gravitation. The Newton is the unit of force in the International System of Units (SI) and is equivalent to 1 kg⋅m/s^2.
