A student and enthusiastic programmer. Love learning Physics! And I make android apps as a hobby.

This will make a great and interesting site : Puzzling. Please follow it

Please support Mechanical Engineering. There are many questions on PhysicsSE site related to engineering, which do not get answered because they are off-topic.

 Jan24 asked Force and Energy of interaction of conducting sphere and point charge Jan21 reviewed Approve suggested edit on Does Super Mario physics work in reality? Jan21 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. Jan21 reviewed Approve suggested edit on If the universe could emerge from nothing, what about physical laws? Jan13 awarded Nice Answer Jan13 comment From where we can view earth moving? You can see the earth moving if you are not moving with it. Jan12 awarded Popular Question Jan9 answered Deriving torque equation from Newton's 2nd Law Nov22 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. Nov21 reviewed No Action Needed How to quote answer when error is smaller than significant figures of data? Nov21 reviewed Looks Good Good and simple reference for studying about ADM mass Nov21 answered Atwood machine problem Nov21 answered Why a system should be at its lowest energy state for its stability? Nov15 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. Nov14 comment Initialize a traveling wave in a 1D gas? can show a diagram of how it breaks into two rarefaction waves? Nov10 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 $2\pi/\omega$. Nov8 reviewed Approve suggested edit on The harmonic oscillator - ladder operators Nov8 answered Artificial Gravity Nov7 comment Determine if an object is in orbit @MrUniverse, If you want to plot a perfect trajectory of an object under influence of multiple massive bodies, you'll have to solve the kinematical equations using newtonian gravity, which is possible(I think) but tough and no general solution usually exists. So you will have to compute the trajectory for every case separately. Nov6 comment Determine if an object is in orbit @dmckee, you can make it a multibody situation by making some assumptions, like multiple point like satellites(negligible mass) orbiting around a massive body(earth). In that case you can neglect the gravitational effect of the satellites on each other, and the program can still be a very useful real world simulation.
