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.
Which of the following is a true statement about the acceleration ~a of the pendulum bob. ~a is equal to the acceleration due to gravity. ~a is perpendicular to the bobâs trajectory. ~a is equal to the instantaneous rate of change in velocity. ~a is tangent to the bobâs trajectory. Reasoning: Acceleration is de ned as the instantaneous rate of change in velocity.
