 Mar 23 comment Can effect of gravity be broken (counteracted) by electric force? Kinda like Millikan's Oil Drop Experiment ? Mar 23 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) Mar 23 revised Where does gravity get its energy from? Fixed typo Feb 1 accepted Light behaves as a particle or wave in this thought experiment? Jan 24 asked Force and Energy of interaction of conducting sphere and point charge Jan 21 reviewed Approve Does Super Mario physics work in reality? Jan 21 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. Jan 21 reviewed Approve If the universe could emerge from nothing, what about physical laws? Jan 13 awarded Nice Answer Jan 13 comment From where we can view earth moving? You can see the earth moving if you are not moving with it. Jan 12 awarded Popular Question Jan 9 answered Deriving torque equation from Newton's 2nd Law Nov 22 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. Nov 21 reviewed No Action Needed How to quote answer when error is smaller than significant figures of data? Nov 21 reviewed Looks OK Good and simple reference for studying about ADM mass Nov 21 answered Atwood machine problem Nov 21 answered Why a system should be at its lowest energy state for its stability? Nov 15 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. Nov 14 comment Initialize a traveling wave in a 1D gas? can show a diagram of how it breaks into two rarefaction waves? Nov 10 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 $2\pi/\omega$.
