Deriving the centripetal acceleration formula. A body that moves in a circular motion (of radius r) at constant speed (v) is always being accelerated. The acceleration is at right angles to the direction of motion (towards the center of the circle) and of magnitude v2 / r. The direction of acceleration is deduced by symmetry arguments.
The acceleration of an object carrying out simple harmonic motion is given by. The positive quantity [omega]2 xm is the acceleration amplitude am. Using the expression for x(t), the expression for a(t) can be rewritten as. This shows that the acceleration is proportional to the displacement, but opposite in sign.
