Relativity #33 - Inertial Frames

Notes are on my GitHub! github.com/rorg314/WHYBmaths In this video I discuss an important feature of special relativity, the notion of 'inertial reference frames', where inertial means travelling with a fixed velocity (subject to no acceleration). We will realise that Lorentz boosts are 'inertial' transformations, in that they transform between reference frames that are moving relative to each other with some constant velocity. This can be understood from the fact that we are dealing with a linear transformation, whose derivatives w.r.t t, x are also zero (leading to the d/dt v = 0 condition). This does not mean that relativity cannot deal with acceleration/forces, but simply implies that a frame that accelerates is NOT an inertial frame, and cannot be obtained by a Lorentz transformation. The concept of non-inertial reference frames will have to wait until we reach General Relativity!
