Learning Outcomes

On successful completion of this module students should be able to:

  • Describe the basic principals of Dynamics, Special Relativity and Quantum Theory and their implications for describing classical and microscopic phenomena.
  • Appreciate applications in predicting planetary motion, in describing space and time and in analysing the electronic properties of atoms and solids.
  • Interpret the physics of rotational motion, of radioactive decay rates and of the forces between atoms.
  • Solve simple numerical problems in Linear and Rotational Dynamics, Special Relativity and Quantum Physics.

Brief description

This module serves as a first introduction to modern physics from a starting point in classical physics, aiming to provide an understanding of the principles of both. Two strands to the module run side-by-side: the first concentrating on classical kinematics, Newton's Laws, energy and momentum and rotational motion, with an introduction to Special Relativity and its implications for describing space and time. The second strand introduces the fundamentals of Quantum Theory at a simple level, applied to explain the properties of atoms, molecules, solids and nuclei. An emphasis will be placed on the solution of problems related to concepts and example sheets will include numerical exercises.



Kinematics: Newton's laws of motion; inertial frames; Galilean transformations; relativity principle of Newtonian mechanics; momentum and kinetic energy; collision processes; internal forces; centre-of-mass system.
Gravity and weight.
Universal gravitation: g and G; variation of g for terrestrial observer; planetary motion and artificial satellites.
Potential energy and gravitational fields.
Rotational motion: centripetal acceleration/force; moment of inertia; equation of motion; angular momentum; analogy between linear and rotational motion.


Introduction and discussion of the shortcomings of pre-relativistic physics, which lead to the simple postulates of Special Relativity, with spectacular results in our understanding of space and time. The Lorentz-Einstein transformations are derived from the postulates, leading to an understanding of time-dilation and Lorentz contraction.
