SUMMARY

A conservative system is defined by the constancy of mechanical energy, represented by the equation Em = Ekin + Ep = constant, where Ekin is kinetic energy and Ep is potential energy. In such systems, while kinetic and potential energies fluctuate, their total remains unchanged over time, indicating that energy is conserved throughout the motion. This principle highlights that although individual energy components are not constant, their sum is invariant, demonstrating the interchangeability of kinetic and potential energy during motion.

Hi,

A conservative system has constant mechanical energy basically.
Em= Ekin + Ep=cte where Ekin is the kinetic energy and Ep is the potential energy.
 
conserved system have energy which are constant of motion?
It means that both kinetic and potential are time independent.
Can we say that these quantities are constant of motion.

No they are not individually constant of motion but their sum is. Typically the kinetic energy is converted into potential energy and vice versa during a trajectory undergone by a conservative system.
