1 PHYS171 Prof. Arthur La Porta [email protected] Rm 1111, IPST building (building #085) Chapter 6 Circular Motion For uniform circular motion we previously derived r v a c 2 = Newton’s second law implies that a force must be applied to maintain this motion r mv a m F c 2 = = This allows us to determine the orbit that would be produced by a given force, or to find the force implied by an orbit at a given speed and radius.
