... Centripetal Acceleration is the acceleration that an object undergoes when it moves in uniform circular motion (constant speed). This is a vector, directed toward the center of the circle with magnitude given as a c = v 2 / R . Here v is the speed of the object and R is the radius of the circle. Ima ...
