Physics – What is it?
Physics is a branch of science concerned with the nature and properties of matter and energy. The subject matter of physics includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms. The world of Physics is an exciting but daunting field of study and spans many different aspects of our universe.
We develop different theories to understand and predict the world around us. Experiments are then conducted to validate or disprove our original theory. Theory, without practice would be very boring and very difficult. For this reason, we conduct regular experiments and visit industry where many of the theories can be seen in action and the power of our knowledge be harnessed to benefit mankind.
Our Year 10 & 11 students recently conducted experiments to prove Ohm’s Law. Definition: a law stating that electric current is proportional to voltage and inversely proportional to resistance.
