For 10 points, name this physical quantity, the rate of change of velocity, symbolized a.
For a body in simple harmonic oscillation, this quantity equals negative the square of angular speed times displacement. One form of this quantity equals velocity squared divided by the radius. It is the second derivative of (*) position with respect to time, and by Newton's second law, is equal to net force over mass.
