. Non-Inertial Co-ordinate systems
A co-ordinate system fixed in the Earth is not an inertial
system since Earth it self is rotating in space. There are
many important effects that result from the non inertial
nature of the Earths co-ordinate system.
The Time-Dependent Schrodinger Equation (TDSE)
This basic equation of non-relativistic quantum mechanics was proposed by E. Schrodinger in 1926
and is also called the wave equation.

The Uncertainty Principle
1. (a) State the two commonly used forms of the uncertainty principle and give a brief explanation of
each of them.
(b) Why is the effect of the uncertainty principle not noticeable in our
PH 4010 - Quantum Mechanics II
1. When proving that the Ehrenfest's equations are equivalent to Newton's equations of motion
one has to use the fact that F(x) = F(x). Discuss under what circumstances this
condition is approximately valid. (Read p
Rigid Body Motion
A rigid body is defined as a collection of particles
whose relative distances are constrained to remain fixed
regardless of forces acting on it.
Such bodies do not exist in nature since the atoms which
comprises the body undergoes some r
A superstructure on Lagrangian theory known
as the Hamiltonian theory was constructed by
an Irish mathematician and physicist Sir
William Rowan Hamilton (1805-1865).

In many cases it is impossible to solve Hamiltonian
equations of motion. One way to simplify the equations of
motion may be through a transformation of coordinates.
Sometimes in a particular dynamical problem it is
Theory of Small Oscillations
A common form of motion of mechanical systems is small

Hamilton - Jacobi Theory
In physics, the HamiltonJacobi equation (HJE) is a
reformulation of classical mechanics and, equivalent
to other formulations such as Newtons Law of motion,
Lagrangian mechanics and Hamiltonian mechanics.
