as you all know, with a set of identical metal balls, lining them up, when i use one to strike them, by the conservation of momentum, the last one in the queue will move on with the same velocity as the first ball(that was pushed by me) (assume friction is neglegible and the experiment is done in vacuum.)O -----> OOOOOO OOOOOO -----> Oso now, my question is,if I put a magnet on the second ball like that:O -----> "OOOOOO (" = magnet)i use the same force to push the first ball, wif the same initial velocity, but when it approaches the set, the magnet will attract the ball and the ball will be accelerated instantaneously. So the 'cannon' shot out will have much larger momentum than the one before. O"OOOOO ----------------> Oi want to ask that, the 'cannon' shot out in this situation, if compared to a metal ball only repelled by a strong magnet, will it have a higher momentum and kinetic energy?
ha, light arrow, i m not trying to get the patent of this system, it's just a little experiment carried by me and a few fds of mine at school as a science demonstration.that's an interesting suggestion about the halving size of balls
