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.
â¢ The centripetal acceleration vector points toward the center of the circle, BUT the velocity. vector always points in the direction of the motion (tangent to the circular path). In uniform. circular motion, Velocity and centripetal acceleration are always perpendicular to each other.
