That is the sum of mass and energy in a closed system is constant. ( If you still like to think of the conservation of mass then think that mass and energy are equivalent and hence if you say that mass, which is equivalent to energy is conserved then the principle still holds).

WebMar 11, 2024 · $\begingroup$ In order for mass to be converted to energy a sub atomic particle must be annihilated which is not the case in a chemical reaction. While it is interesting you can use E=mc2 to convert the energy into an apparent mass, it is off base. When an 100g apple falls from a 1m tree do we say 0.98J was converted to mass and … Web8.2. Conservation of mechanical energy. A mass hanging from the ceiling will have a kinetic energy equal to zero. If the cord breaks, the mass will rapidly increase its kinetic energy. This kinetic energy was somehow stored in the mass when it was hanging from the ceiling: the energy was hidden, but has the potential to reappear as kinetic energy. spanish sweetheart crossword clue https://bridgeairconditioning.com
