However, what you're losing is not fat and it's not safe weight loss. To gain better perspective, let's define what the paradigm of weight is: Weight is nothing more than the force of gravity pulling an object toward earth! Here's a test for you. Go weigh yourself. As soon as ...

The symbol “g” is “gravity” represented by its initial letter, so that if the meaning of the word be changed, consistency would require that the symbol should be altered. I find, practically, no difficulty in restricting the word “weight” to the sense of force, insisting on the use...

Just jump up and down (gently!) on your scales at home to see your apparent weight change, while your mass stays the same.So your mass is the same, and your weight is the same (because the force of gravity hasn't changed), but your "apparent" weight changes. Read more at Apparent...
Weight is the force of gravity. It is equal to the mass of the airplane times the local gravitational acceleration, i.e. the local gravitational field. You can measure the acceleration of gravity by observing the motion – relative to your chosen reference frame – of a freely falling object...
The terms "mass" and "weight" are used interchangeably in ordinary conversation, but the two words don't mean the same thing. The difference between mass and weight is that mass is the amount ofmatterin a material, while weight is a measure of how the force of gravity acts upon that ma...
