If a free body could be positioned at decreasing distances from the center of the earth, the mass of the earth would become more distributed around the free body, until at the very center of the earth the net gravity on the body would be zero. At this point the mass of the earth (and the force of gravity) would be uniformly distributed in all directions.

Will you weight the same on the moon as you do here on earth?

You will be lighter on the moon than on earth because the gravitational pull is different on the moon than on earth. That gravitational pull difference will make the weight different. A 100 lb person will weigh about 16 lbs on the moon.

Explain the difference between "mass" and "weight" . if a NQ drill rod has a mass of 7,6kg per meter, what is the weight of a 3 meter NQdrill rod?

If the rod has a mass of 7,6kg/m then 3m of it will mass 22.8kg.

Mass it the amount of matter. Weight is the force exerted by the mass in a gravitational field. If you have an object massing 22.8kg, the mass of it will be 22.8kg whether you're on Earth, the Moon, or in outer space. It will weigh 22.8kg at the surface of the Earth, about 4kg on the Moon, and nothing (weightless) in outer space.

How did life start in the universe

Lots of theories and beliefs, but we don't know, because, well, we weren't there! I personally lean toward the whole higher power thing, because, frankly, believing that complex creatures just kind of "fell together" (the way matter coalesces into planets and stars, basically driven by gravitational forces) seems a bit far-fetched. If I'm right, we'll likely find out at some point. If not, then it won't matter, because we'll just be gone. Either way, nothing is lost by having a little faith and seeing some purpose to it all. :-)

Facts about the moon

Good question: It assists the earth with gravitational forces that move the oceans and waters. The reflection of the sun give us visible light in the evening.

Where was the salt water goes after the low tide?

Is this for the summer school class that you're taking because you flunked science during the regular school year? It goes to the part of the earth that is experiencing high tide. There's always high tide somewhere... it's generated by the gravitational force from the moon. Shhhhh... don't tell Bill O'Reilly from Fox News, he thinks it's God talking to us.

Which is the lightest metal that acts opposite to gravity ?

It is not possible for any metal (or anything for that matter!) to act opposite to gravity.
Everything has a weight (effect of gravitational pull on a mass), and is pulled towards another mass (in this case Earth) but many things are ligher than air, so they will float away from the earth until the air becomes so thin that its boyant effect is no longer stronger than the gravitational effect, and the objet can rise no further.

I have never used a leveler, I purchased a Stanley 43-512. How do I use it?

Here's how a bubble level works a small tube is filled with liquid allowing only a small pocket of air inside. The concept is that air will always rise to the highest point. The idea is that if you lay this tube horizontal to the earths gravitational pull and the pocket of air goes to one side than that side is higher than the other. If the bubble rests in the center than both sides are of equal height. Your particular level has three bubble dials for vertical, horizontal, and 45 degree placement. Say you want to level a picture on the wall. if you place the level on top of the picture frame you will use the center dial and adjust the frame until the pocket of air sits between the two indicator lines in the tube. You hold the level on the side of the frame, in which case you would adjust using the dial that is perpendicular to the level. the 45 degree would only be used if you want something to be 45 degrees from the gravitational plane.
