Learn more about Gravitational mass

According to Newton’s law of gravitation, the gravitational force on a body is proportional to its mass. We can measure the mass of a body by measuring the gravitational force exerted on it by a massive body like Earth. Gravitational mass is the mass of a body which determines the magnitude of gravitational pull between the body and the Earth. This is determined with the help of a beam balance. If FA and FB are the gravitational forces of attraction on the two bodies of masses mA and mB due to the Earth, then

If one of the two masses is a standard kilogram, the unknown mass can be determined by comparing the gravitational forces.
