1) This week, we introduced a new model, the rigid rotor, that can be used to describe rotating molecules. Before we get into problems that describe the quantum properties of a rigid rotor, let's quickly review the classical behavior of a rotating molecule. Consider a single atom with mass m rotating about the origin in a circular orbit with radius r. If the particle's linear momentum is p...

A Review Learning Goal: To apply the principle of work and energy to a rigid body. Submit Previous Answers Correct Part B The principle of work and energy is used to solve kinetic problems that involve velocities, forces, moments, and displacements. For a rigid body, the principle is Ti + QU1–2 = T2 where Ti is the body's initial kinetic energy, EU1-2 is the work done by external forces and moments that act on the body, and T2 is the...
