Round 5: Tossup 3
This quantity’s operator appears in the exponential form of the time evolution operator. In the QHO, the eigenstates representing this quantity are separated by a factor of h-bar omega. This quantity’s operator contains two terms: h-bar squared over two-m times a second derivative, and V-of-x. In quantum mechanics, this quantity’s operator is represented by the (*) Hamiltonian; thus, H acting on psi equals this quantity times psi in the time-independent Schrodinger equation. The lowest value of this quantity in quantum mechanical systems is the ground state. For 10 points, name this physical quantity, the sum of its kinetic and potential components. ■END■
ANSWER: total energy [accept Hamiltonian until read; reject specific forms of energy like “kinetic energy” or “potential energy”]
