hello sir i am little confused that when we hammering a rigid wall then where the all energy goes supplied by the hammer act. example: suppose i am betting a wall with hammer and there is no effect on wall (mean to say wall is not moving or not creaking). Then tell me where the all energy goes...

thanks its very helpful for me.

but below one person is saying NASA is using ion and plasma fuel because of their heavy mass particle. because at the same speed massive particle produce more momentum. So it provide more thrust to propel the rocket. i am confused NASA is using light particle fuel or heavy particle fuel

The only way to get energy from near by star is using PV panels. But We need hug amount of energy to propel spacecraft in space. SO we need big amount of panels. Means more mass and big system. It would be very hard for us to push out from Earth gravitational field.

thanks to share your views.

lets understand this with the help of practical example... suppose you have a piston and cylinder system contains gas in it and assume that system is isolated from surrounding. Mean no heat and mass transfer in surroundings. System isolation means the total enthalpy of system remains constant...

Is making photon Engine possible ? :A different thought to power space craft! Now a days Scientists are working on photon engine. They are trying to power engine from light. Thought is looks great but there is practical engineering problems with it. Ya it is true that photons have momentum...

I am confused some people are saying Gravity has speed of light and some are talking about infinite speed. Friends tell me what exact is speed of gravity. If you have any way to demonstrate it please share with me. ok and my new question is why matter has mass?? tHANKS

Actually you can say heavy mass object have more inertia then littler objects. More will be the mass of object it will take more force to get accelerate. In case of low mass object it will take less force to get accelerate.

I will come back with come great videos ...

ya ...but this is just a illustration thanks for comments

NO need to confuse over it. Just Take it easy. I try to make it clear. Actually the rate of work done is called power. I mean for calculating the power you must know the work done. ... Work done per sec is called power and measured in Watt. Work done per minute is also power. Work done per hour...

In the morning i get this idea ...the simplest way to determine friction force between two sliding surfaces. http://www.youtube.com/watch?v=T2jWT9r2Z-U&feature=plcp
