What is Physics?

Physics is the branch of science that studies matter, energy and the relationship between them. Understanding the laws of Physics gives us a better view of the world we live in. If you are curious enough to wonder about any of the following questions, then you should enjoy studying Physics. 


  • Why do I see colours on my C.D?
  • How does a generator produce electricity?
  • Why is there sometimes a rainbow when it's wet?
  • How can we see inside a person's body with an X-ray machine?
  • How do the speed guns of the Gardaí work?
  • What are mirages and how do they occur?
  • Why do vibrating waves produce sound?

In Leaving Certificate Physics you will study various topics in each of the following areas. Mechanics and Motion (5th year), Heat (5th year), Waves and Sound (5th year), Light and Optics (5th year), Electricity and Magnetism (6th year), Atomic Physics and The Electron (6th year) and Nuclear and Particle Physics (optional)

There are 25 compulsory experiments in Leaving Certificate Physics. Four of these are asked in Section A of the exam and you must answer three. Pupils generally do well here as we focus a lot of attention on experiments and we tend to repeat them closer to exam time. In addition, some of these experiments can be asked in Section B.
