Tutorial
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

2 Nuclear Forces
In discussing nuclear forces we first point to the differences between nucleons
in nuclei and electrons in atoms. In the latter case the electrons are bound by
the coulomb potential due to the electric charge of the
Discuss 4 independent arguments against electrons existing
inside the nucleus.
If a nucleus (A,Z) were to consist of A protons and (A-Z)
electrons, the spin of an odd-odd nucleus or an odd-even nucleus
would not agree with experimental results, Take the o
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
Hamiltonian Theory
A superstructure on Lagrangian theory known
as the Hamiltonian theory was constructed by
an Irish mathematician and physicist Sir
William Rowan Hamilton (1805-1865).

Canonical Transformations
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
oscillations of a system about the position of stable
equilibrium.
The theory of small oscillations is in general an

introduced in 1833 by Sir William R.

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.

. 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.
