Who invented the formula for Kinetic Energy -LRB- KE = 1/2 mv ^ 2 -RRB- and when should it be used instead of the formula for momentum -LRB- p = mv -RRB- and why ?
Can an electron have zero distance to the nucleus ? If yes then E = mv ^ 2/2 - Ke ^ 2/r will be there infinite energy ? Maybe when an atom is fully shrinked ?
