WebCentripetal acceleration is calculated with ac=v2/r where v is the orbital speed and r is the radius of the orbit. First, find the orbital speed using the distance traveled in one period: v=2πr/T where 2πr is the circumference of the orbit and T is the period. The centripetal acceleration can then be expressed as ac=4π2r/T∧2.
