Unit 5 Overview

Part A

This unit looks at the key discoveries that led to modern physics as we understand it and apply it.

 

Radioactivity was a key discovery in the late Nineteenth Century.  As well as being an interesting phenomenon in its own right, it also enabled physicists to look at the atom in more detail.  This in turn led to the ideas of nuclear physics

 

Nuclear Energy is a spin-off from nuclear physics.  Although its application in weaponry is terrifying, the energy can be put to peaceful use in nuclear power stations.  Although nuclear power remains highly controversial, the technology can meet our energy needs with very little carbon emission.

 

Thermal Physics studies the behaviour of flows of heat energy, and the way gases behave when they are heated.  These ideas are fundamental to engineers as they design heat engines.  Thermodynamics is an important part of Applied Physics.

 

Part B

This part has the five Options, of which you choose one (or, more likely, your Physics teacher chooses it).  If there are lots of A-level groups in your school or college, you may get the choice of which one you do.
