Well here's on of the articles that explains it better than l can lolNo if the force is greater here what is the force that is causing the molten lava in the core. The lower you go the stronger gravity is. Just like the further away from earth you are the less effect its hold has.
This was one of the "blackboard problems" i remember from physics class. At the earth's center of mass, the local gravitational effect is nearly zero, with the "nearly" being solar and lunar tidal offset. A body only experiences weight from the mass below it. The spherical shell above a subsurface object still exerts gravity, but it cancels out. Zero vector sum. At the center of mass, all the planet's weight is above and cancels itself out.Actually...l've heard more than once that gravity is stronger on the surface, moreso than at the center of the earth...something about the forces of matter in the middle cancelling each other out...not saying it's true, but l've heard something along those lines multiple times
what did the tank see? it saw the same exact thing you did, except opposite. it saw YOU moving away from IT at the same rate you claimed to see the tank move away from you. it all depends on what your perspective is. just like the paper-earth analogy.Two objects in space, one a Sherman Tank and the other, myself. if I push the Sherman tank, I will move away, not the Sherman tank. Someone stated that two objects of different masses would move away at the same rate, but that is simply not true.
you only see that effect because there are third party objects that both people can relate to. if the two pushed eachother in space, you cant say the smaller massed person moved and the big one didnt because you have nothing to relate that motion to except eachother.The object of lesser mass will move, and not the larger, each and every time. Get some rolly chairs, and a few different weighted friends, give it a try. Applies in space too.
size is not the issue. mass is what determines gravity. why would it not have gravity without a core? if it is made of matter and has mass, it has gravity.Just because an object is the size of Jupiter, doesn't mean it has the same gravitational feild as Jupiter, it COULD not have one at all if the structure is coreless.
May I ask where you went to school?But IT WOULDN'T be able to escape be cause the gravity around it would be so great. It may have 0 gravity at the exact center. But you try getting something at the center out with a magnet from a foot a way. I don't care if you've got a 40lb magnet. That paper clip isn't coming.
At least you're able to explain it off the top of your head...l had to google LOL<edit> In the time it took me to formulate this post, I've been anticipated.
size is not the issue.
That is an entirely different subject, which has been said, only proves to contain forces greater than that of gravity.

Of coarse a concentrated magnetic to a piece of steel will unite before they both unite with the ground, however, when you let go, they will both fall to the ground. You are only representing a tighter bond within the realm of gravity. we already KNOW that certain metals are magnetic and attract to one another. but this does not correlate with the actions of gravity.
okay apparently you still dont get it. im not saying gravity disappears and magnetism takes over. im saying a small magnet can have enough force to attract a paperclip into the air. this means the entire earths gravity was not strong enough to hold the paperclip down against the magnetismRub a ballon on your head and stick it on the wall, does that mean gravity is static? No, its a stronger force that isn't entirely relevant.
I can also overcome gravity by picking up a dime off the floor...superhuman, right hereokay apparently you still dont get it. im not saying gravity disappears and magnetism takes over. im saying a small magnet can have enough force to attract a paperclip into the air. this means the entire earths gravity was not strong enough to hold the paperclip down against the magnetism
[video=youtube;cP0Bb3WXJ_k]http://www.youtube.com/watch?v=cP0Bb3WXJ_k&feature=related[/video]anyone who tells you that every object in space has the same mass is a joke. I'm done.
Laws apply on Earth, but to say the moon has an equal mass or equal gravitational pull is wrong. Otherwise we would spin together, instead of having the smaller mass remain one-sided, always having the opposing side facing away. Clearly, we have a greater gravitational pull. All that guy did was ask a bunch of people a question and get the "wrong" answer he knew he'd receive, only so he can recite someone else's theory. That might be your definition of smart, but I differ.
Trusting laws which are evidently not accurate or relative is the Achilles heal of society. If this is about science, then I'm out. I was under the assumption this was about what we know.
i knew it! that bitch! lolWhoever told you that ... she lied.
okay so the force you exert 'on the tank' by pushing it is 'split' between the two objects?In the Sherman tank example, conservation of momentum is the thing. The tank moves; the person moves. What does not move 9or change velocity/direction) is the center of mass of that two-body ensemble. But you know that. I'm just tilting at the clarity windmills. Sancho! My armor ... !!
cheers 'neer
You are extremely hostile to people that wanted to help you clear up misconceptions. What makes you think you are more correct about these things than the actual scientists that study them?No you can't. You've lurked me enough. Can I ask if you drink blue ribbon and won't pull the stick out of your ass?
No, it means that you are able to overcome the force of gravity on the paperclip with just your muscles. You can also pull the paperclip away from the magnet too so you might think you are stronger than magnetism. However, I can produce a magnet that you would not be able to pull it away from. At short distances, magnetism is extremely strong but does not work over distance. Even though gravity is very weak, it acts over enormous distances.I can also overcome gravity by picking up a dime off the floor...superhuman, right here
