Why, the weight of an object on moon is one-sixth of the weight of the same object on earth?

Weight of on object = W = mg
 
Where g = acceleration due to gravity
 
The value of g varies from plae to place.
 
In order to calculate weight on earth we substitute 9.86 m/s^2 in the formula.
 
 

After substituting all the values, value of g on the surface of the moon approximately  comes out to be,
g = 1.63 m/s2
 
This value is approximately 1/6th of value of g of earth.
Therefore the weight of an object on moon is one - sixth of the weight of the same object on earth.

A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are): a. A downward force of gravity along with a steadily decreasing upward force b. A steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth c. Constant downward force of gravity along with an upward force that steadily decreases until the ball reaches it highest point on the way down there is only a constant downward force of gravity d. Constant downward force of gravity only
