DESCRIPTION

6/3 Erwin SitompulUniversity Physics: Mechanics Uniform Circular Motion  The magnitude of this centripetal acceleration a is: → where r is the radius of the circle and v is the speed of the particle.  In addition, during this acceleration at constant speed, the particle travels the circumference of the circle (a distance of 2πr) in time of: (centripetal acceleration) (period) with T is called the period of revolution, or simply the period, of the motion.
