## Weighing Scale and Gravity

Hi. I'm an absolute noob at physics, so I went to the library and checked out a couple beginner books. Basic Physics: A self-teaching guide and Science 101 Physics.

I'm just getting started reading physics 101 and read the following statement:

"...all you have to do to determine your weight is step on a scale. What is actually being measured in this case is the gravitational pull of the Earth on your body."

It then goes on to talk about your weight on other planets, etc.

I'm wondering why the earth pulls harder on me when I'm fatter. I hope that question makes sense. I just can't see why the gravitational pull is greater for a bowling ball than it is for an apple.

Thanks for any clarification.

 You said you are starting physics now...So start it and go on further you get to know why it is on your.. from Newton's gravitational law , gravity between two objects proportional to the product of the masses directly and inversly to the square of the distance between them,.,,, So you conclude why a ball is pulled with greater force that an apple or why you weigh more when you are fatter...(means more mass)
