Quiz on Equations of Motion and Quantum Mechanics

What is the primary purpose of the equations of motion in physics?

• To determine the energy levels of a system

• To study the motion of physical systems

• To analyze wave functions

• To calculate the mass of particles

In the Schrödinger picture, which of the following remains constant over time?

• The Hamiltonian

• The expectation value

• The state vector

• The operator

Which picture involves both the state vector and operator changing with time?

• Heisenberg picture

• Interaction/Dirac picture

• Classical picture

• Schrödinger picture

What happens to the state vector in the Heisenberg picture?

• It is fixed in time

• It varies with the Hamiltonian

• It is time-dependent

• It is not defined

In the interaction picture, what does the Hamiltonian consist of?

• Only the unperturbed Hamiltonian

• Only the perturbed Hamiltonian

• Both unperturbed and perturbed Hamiltonians

• Neither unperturbed nor perturbed Hamiltonians
