Acceleration due to gravity: The acceleration achieved by any object due to the gravitational force of attraction by any planet is called acceleration due to gravity by the earth.
As each planet has a different mass and radius so the acceleration due to gravity will be different for a different planet.
Weight: The weight(w) of an object is the force of gravity on the object and may be defined as the mass(m) times the acceleration of gravity(g).
Weight is a force, the SI unit of weight is Newton.
Weight (W) = m g
Where m is mass and g is the acceleration due to gravity.
Mass of the moon is 1/100 times and the radius of the moon is 1/4 times that of the earth.
Since the acceleration due to the gravity of the moon is one-sixth of that of the earth.
So Weight of any object on Moon = 1/6 × Weight of any object on the Earth surface.
EXPLANATION:
Given that:
The weight of any object is 600 N in an earth surface
The weight of the object on Moon = 1/6 × Weight of any object on the Earth surface = 600 × 1/6 = 100 N
