Description
This presentation is a continuation of one I gave on April 1, 2022 on the velocity triangle and the Brehme Angle as a graphical solution to problems in Special Relativity. This presentation applies those concepts to a body undergoing uniform linear acceleration, to determine that linear acceleration is rotary motion in four dimensions. The simple graphical solution satisfies the classical equations of motion v=at and s=1/2at2 at small angles of rotation (v<<c), and observed relativistic mass rise for rotational angles for greater velocities. The simple trigonometric model predicts that an unaccelerated observer will measure the body’s location along a hyperbolic worldline, consistent with the trajectory derived in Gravitation (Misner, Thorne and Wheeler) using tensors.
