A form invariance for mechanical systems with second_order reducible differential constraints is studiedTwo methods to study the form invariance of the systems are usedIn the first methodthe system is considered as a nonholonomic system with second_order and in the second method it is considered as a system after reductionThe relation between the two methods is obtainedThe result proves that it is possible that some symmetries are lost in the second method
