In quantum mechanics, its standard form is minus h bar squared  over two m times the Laplacian (la-plah-see-en), plus the potential  energy.
In quantum mechanics, its standard form is minus h bar squared  over two m times the Laplacian (la-plah-see-en), plus the potential  energy. In classical mechanics it is not an operator but a  quantity, usually calculated as p squared over two m plus the  potential energy. For ten points, give the name of this  observable, generally associated with a system's total energy.
