The force of gravity is dependent on the masses of the objects and the inverse square of the distance. No matter how close you bring the two apples, their mass is so small compared to the other masses acting on them (primarily the Earth itself).
When you throw an apple into the air, it will fall back down to the ground. At the same time, the Earth actually "falls" toward the apple. However this "fall" is so small that you can't measure it.

Engine stalls at 50mph or when low on fuel


when low on fuel and the you drive and you turn car , side gravity forces force the fuel from the pump sock pickup sock and the fuel pump stalls, read the op. guide it tells you not do that.
the pump is fuel cooled, an fuel lubricated and starving it is a bad ACT.
so say what is going on at 50mph, going up or down a hill with 1/8th tank of fuel?

my jeep stalls in fast turns at 1/4 full (1991) slosh effect.
i slow down and bingo, it runs. did so new, and so did others..

gravity (and inertia) are our friends, but not always.
see space movie called Gravity. friend and foe.

How dose gravity work


Gravity is a mutual attractive force between any 2 bodies (masses). It is classified as a weak force (by comparison with molecular forces) but is thought to be unlimited in range.

It increase with the masses of the attracted bodies, but decreases with the square of distance, so that if you go twice as far from Earth, the effect of gravity on you is lessened by a factor of 4.

So this means that a huge fully loaded oil tanker is attracted to the wharf, which is attached to the Earth. Such forces usually can be ignored, but not when launching rockets for instance.

It is thought that a theoretical particle called the Graviton influences gravity by interacting with something in Einstein's Theories called a stress-energy tensor. The trouble is that the Graviton has not been detected, so other theories about what makes gravity are possible.

No work is done by gravity on a bowling ball that is rolled along a bowling alley because why?


If the bowling alley is perfectly horizontal, the center of gravity of the ball will remain at the same height measured in a fixed system of reference. As you know the gravity force is directed vertically downward. To calculate the elementary work of that force you evaluate the inner product dW= vec(g).differential of vec(5). However since the displacement vector vec(r) remains in a horizontal plane ( Prependicular to the direction of vec(g), and the ball does not bounce and leave the horizontal plane) the angle between vec(g) and vec(r) is equal to 90 degrees. the inner (scalar product is =0).

A simpler way to remember it is that the work is equal to g*(difference in height)

How does a sattelite fall if there is no gravity in space


Gravity is a force that causes a mass/object to be attracted to another mass/object similar to magnetism. Gravity is not an object itself located in any particular place like earth or space.
The satellites stay in orbit around the earth because the force propelling the satellites forward away from the earth is balanced by the gravity pulling them back to earth.
The satellites move too slow and they fall back to earth. If they move too fast, they fly out further into space and out of orbit.
I hope this answers your question.

Y is the earth shaped like a sphere?


Because Gravity pulls equally in all directions. When the Earth was forming, it was entirely molten rock. And, since Gravity pulls equally in all directions, the Gravity of the Earth pulled the molten rock into a sphere.

You have a cotto ag and a iron bar of same mass of100 K .on weigihng it on a weighing machine which is heavier?


Neither. Both weigh the same. W = G x M where "W" is Weight, "G" is the force of Gravity and "M" is the Mass of the object.

If the mass of two or more objects are the same, and subjected to the identical force of gravity, the two objects weigh the same.

I hope this helps!

Gravitational force goes on decreasing towards the center of the earth.why?


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.

My toto toilet has both 1.6 gal and 6 gal flushes. the short flush doesn't go down.


I am not a toto expert but i think i understand the gravity control toilet concept.A gravity flush tank type toilet flushes do to the force of water traveling from the tank to the bowl in a small passageway and forces the water in the bowl towards the integral trap in the toilet.In other words the water isnt dumping quick enough or the passageway is restricted.,My guess is the flush valve isnt dumping all at once.

Why the potential energy is unlimited?


Its all about what"creates" the force and not the force itself.Force is a by product of an earlier process.Gravity is a good thing but its only free one way takes energy to get back up the hill.Very bazaar topic to post on fixya not sure what sort of answer your after but it was good to consider something outside left field.Good luck with your search for a global solution.
