weight = mass x gravitational field strength
|
|
|
gravitational field strength = mass x weight
|
|
|
mass = gravitational field strength x weight
|
|
|
mass = gravitational field strength ÷ weight

Detailed explanation-1: -The weight of an object and its mass are directly proportional. For a given gravitational field strength, the greater the mass of the object, the greater its weight. Weight can be calculated using the equation: weight = mass × gravitational field strength. W = m g .
Detailed explanation-2: -The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.
Detailed explanation-3: -Newton’s law of gravitation is: F = GMm r2 where the Gravitational Constant G = 6.673 × 10−11Nm2kg−2 (kg−1m3s−2). gravitational force per unit mass = gravitational acceleration g. g is approximately 9.8m/s2 at the surface of the Earth.
Detailed explanation-4: -Gravitational Force = (Gravitational Constant × Mass of first object × Mass of the second object) / (Distance between the centre of two bodies)2.
