(provided the driver does not brake). The direction of the velocity vector is changing. A force is required in uniform circular motion.Centripetal Force & AccelerationSince an object in motion will travel in a straight line (Newton ’s First Law) an force must be required to accelerate the mass . This force does not cause a change in velocity as stated in the introduction‚ but rather it is responsible for the change in direction. The centripetal acceleration (ac) is equal to the square of the velocity
