simple harmonic motion

Question Simple harmonic motion (SHM) is a technical term used to describe a certain kind of idealised oscillation. Practically all the oscillations that one can see directly in the natural world are much more complicated than SHM. Why then do physicists make such a big deal out of studying SHM? & ... Read More
