Physics

Course summary

Why study physics at A-Level, you may be wondering to yourself? Physics aims to answer the almost childlike, but deeply profound question… why is everything the way it is? Take pretty much any statement and ask yourself “why?” just a few times, and you will quickly find yourself in the realm of physics. The table is white. Why? Because the paint is white. Why? Because the atoms that make up the pigment in the paint reflect all colour frequencies of the visible light spectrum, and the human brain perceives this mixture of all colours as white… physics! Aunt Betty fell over. Why? Because she slipped on the ice. Why? Because ice is slippery. Why? Due to the atomic structure of solid water, applied pressure to the surface can momentarily cause a nano-thin layer of ultra-viscous liquid water to be formed between the ice and Aunt Betty’s shoes, and this strange layer has many of the physical properties of oil – Including its slipperiness! Physics again!
