how does it work

Okay, think of space like a big, fluffy pillow. Now, drop a marble onto the pillow (In your mind). What happens? Little dent in the pillow, with the marble at the center. Now, drop a bowling ball on the pillow. HUGE dent with the bowling ball at the middle. That's gravity in metaphor.
(Also, when I refer to space, I don't mean just outer space, I mean ALL space. space between you and the couch (Yes, even YOU exert a teeny tiny gravitational pull) space EVERYWHERE is a big, fluffy pillow.)

Einstein found that what we call gravity is actually a distortion or bending in the geometry of space caused by the presence of mass. Imagine a thin rubber sheet with a bowling ball resting on it. Where the bowling ball (..mass..) sits the rubber sheet (..space..) is distorted. That distortion represents the force of gravity. Further imagine that the surface of the rubber sheet is coated with a thin layer of oil. If you got too close to the edge of the dimple caused by the bowling ball you'd slide down it, just like gravity pulls you downward.
This isn't just theory either but scientific fact proven over and over again by precise experimentation. Since Earth has mass, the shape of space around it is bent and warped.

Think of gravity not as a force in and of itself...but rather a reaction to the environment. Gravity is most simply explained as "the act of falling into" . basically we are pinned to the surface by the downward draw created by the planets mass....we have "fallen" onto the planet.Getting out of our atmosphere is like chugging up a steep hill..... the amount of energy needed to reach the top far exceeds the energy/force being put out by the hill ( this being almost none...the hill is just there ) This is a basic analogy of why gravity is one of the weakest measurable forces....but has the greatest impact.

according to sir isaac newton ,
the force of attraction b/w 2 bodies is directly proportional to the masses of the 2 bodies and inversely proportional to the square of their distances........
hence solely the gravitation force depends on the mass and distance b/w the 2 bodies.....
in case of the earth also its the same . because of the earth's mass we do feel the force of attraction towards it....
for instance , the mass of the moon is 1/6th of earth's mass
hence the gravitation force on moon is 1/6th of earth's.......
