Question

what is gravitational mass? write down its expression.​

Answer 1

Answer:

Restated in mathematical terms, on the surface of the Earth, the weight W of an object is related to its mass m by W = mg, where g = 9.80665 m/s2 is the acceleration due to Earth's gravitational field, (expressed as the acceleration experienced by a free-falling object).

Answer 2

The mass of a body as measured by its gravitational attraction for other bodies is called gravitational mass .

W = mg
