comment Can effect of gravity be broken (counteracted) by electric force?
Kinda like Millikan's Oil Drop Experiment ?

comment Choosing proper centripedal force in Newtonian gravitational forces
What you need is a proper scale-down factor to try and fit large orbits of satellites around the earth onto your screen so everything is visible properly. What you need to scale-down here is not earth's mass, but the radii of the orbits. So let the mass of the earth be the same, and also the definition of other units, and try to simulate the exact distances which would exist. Then scale-down to make the simulation fit your screen (eg. 500 mtrs -> 50 pixels)

comment How can one calculate the distance a particular sound will travel?
There won't be a definitive point where the wave will "stop". The wave's intensity would exponentially die down with distance, and it greatly depends on the conditions of the medium it is travelling through.

comment From where we can view earth moving?
You can see the earth moving if you are not moving with it.

comment Atwood machine problem
The impulse might have deformed the pulley a bit(compressed it), like an inelastic collision. That deformation will produce heat, which leads to loss of mechanical energy.

comment Constant Velocity 'Force'?
Why do you feel it is "actually not a force"? Is it because you feel the force doesn't cause any acceleration to the body it hits? That is not because there is no force, but because all the forces acting on that body cancel out.

comment Period of small oscillations
Given small vertical oscillations, you can assume the motion to be simple harmonic. Then the time period would be given by $2\pi/\omega$.
