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

In this session i need to give a glance on gravitational energy.this is the basic force by which we are able to survive on earth with out falling into the huge empty space of the universe.even though the earth rotates around its own axis @ 1670km/h and revolves around sun @ 108000km/h at this high rate of speeds we may thrown away but not because of this gravitational force only.works on this force started with the initiating works of galileogalilei around 16th century AD . After him many scientists like Newton,Einstien,Charlesdarvin.newton proposed the universal gravitational law which gives all the attractional forces between any two objects in the universe.and also darwin did an experiment which shows the attractional force between the two bodies.

through this gravity only all the planets are revolving around the sun and also the satellites around the planets. based on this theory many laws ,principles ,solutions were further done by many physicists like EQUIVALENCE PRINCIPLE,ENERGY WAVE THEORY,
SCALAR -TENSOR THEORY, ASTRO PHYSICS,COSMOLOGY,DARK ENERGY,QUANTUM PHYSICS,etc...related thorey will be published in next posts thanku

First of all i need to give better clarification.........
1.what is science?
2.what science contains?
3.what it deals?
4.one need to study and learn science why?
All these questions may arrive in your minds even for single time..lets have a brief glance on it....

In the video we have every thing in this universe what science deals with.each and every thing in universe contains science in any part of it.with out science we cant even estimate our life. THIS IS WHY WE NEED TO KNOW SCIENCE TO LEAD OUR STRENGTH FULL LIFE

Hi friends this is Harsha. In this blog i am going to post all the views on wonders of science and creations from past and present technologies from where ever possible by my sufficiency of knowledge through internet and books.so friends be visiting my blog periodically.

with regards,

science and technology lovers......
