This post extends about gravity in the way how it is responsible for the  movements occurring in the universe by a simple lecture...https://www.youtube.com/watch?v=MTY1Kje0yLg
This video lecture represents  how the attraction is possible between the objects and rotation and revolutions of stellar and normal objects...


Can we use gravity for any type of projects?
Yes off course this gravity helps i producing the perpetual motions and movements in the objects which helps in creating huge projects...
 

   
How this motion created.......

 these two videos gives the perpetual motions of the objects under gravity..

 even though the gravity is one type of magnetic forces it varies from place to place and altitudes to depths.

but it varies from planet to planet based on the radius and mass of the bodies.

 Generally the gravity of earth is taken as a constant of 9.8m/s2.
 
F = G \frac{m_1 m_2}{r^2}=\left(G \frac{m_1}{r^2}\right) m_2
 on earth it becomes as 9.8 since the radius of earth is 6.371mega meters and its mass is around 6000*10^24..

g=G \frac {m_1}{r^2}=(6.67384 \times 10^{-11}) \frac{5.9722 \times 10^{24}}{(6.371 \times 10^6)^2}=9.8196 \mbox{m} \cdot \mbox{s}^{-2}
  Even on the surface it changes as the altitudes and depths changes as the radius changes.for an altitude the gravity on earth is defined with
g_h=g_0\left(\frac{r_\mathrm{e}}{r_\mathrm{e}+h}\right)^2 
and at depths it becomes as
g(r) = -\frac{GM(r)}{r^2}.                
 like wise it changes with respect to the bodies on sun it becomes 27 times more and on earth it becomes one sixth....
The other interesting topics about gravity and other cool science topicecan be explained in the further posts keep learning from supersscience.blogspot.com
