Physics is crucial to understanding the world around us, the world inside us, and the world beyond us. It is the most basic and fundamental science. Physics challenges our imaginations with concepts like relativity and wave theory, and it leads to great discoveries, like computers and lasers, that lead to technologies which change our lives — from healing joints, to curing cancer, to developing sustainable energy solutions.
Physics encompasses the study of the universe from the largest galaxies to the smallest subatomic particles. Moreover, it’s the basis of many other sciences, including chemistry, oceanography, seismology, and astronomy (and can be applied to biology or medical science).
Physics at Leaving Certificate is a mixture of practical work and theory. Why is the sky blue? Where does the earth's magnetic field come from? These are some of the questions that arise in Physics. There are about twenty compulsory experiments to be undertaken by the pupils themselves.
Topics include: Mechanics, Heat and Temperature, Electricity and Magnetism, Electrostatics, Atomic Physics, Waves, Sound and Light, Optics, Nuclear Physics and Particle Physics.
Prerequisites: An enquiring mind and an interest in Maths at Higher or Ordinary Level.
Career Prospects: Physics deals with the Laws of nature. It is of fundamental importance in technology and vital for courses in engineering and science. Some paramedical courses require knowledge of physics.
