Question

analyze the formula W= mg to explain how an objects weight can change even when its mass remains constant.

Answer 1

Not sure about analysing, but the mass is how much matter an object is made of and weight is the downward force acting on the object. So, really, when we measure ourselves, we're measuring our mass, not our weight, because mass is measure in grams or kilograms, and weight is measure in Newtons.

Answer 2

Step-by-step explanation:

The weight (W) of an object is given by,

`W = m * g`

where, m = mass of the object

g = acceleration due to gravity

From this it is clearly evident that,

`W \propto g`

We know that mass of an object remains constant irrespective of its location. But the value of g will vary. Lets say if you moved to Moon. There, the value of g is around one sixth of the value of g on Earth. This means that weight of the object will also be one sixth of weight on Earth.
