What happens to the mechanical energy of a system when only conservative forces do work?Select one:a.It is completely converted to heatb.It remains constantc.It increasesd.It decreases

Consider forces, work, and potential energy Complete the following statement:  A force that acts on an object is said to be conservative if...Group of answer choicesit obeys Newton’s laws of motion.it results in a change in the object’s kinetic energy.it always acts in the direction of motion of the object.the work it does on the object is independent of the path of the motion.the work it does on the object is equal to the increase in the object’s kinetic energy.

If the kinetic energy of a system decreases while the system's thermal energy and potential energy are unaltered, which of the following is true? The system is doing work on the environment and the total mechanical energy of the system is higher. The system is doing work on the environment and the total mechanical energy of the system is lower. The environment is doing work on the system and the total mechanical energy of the system is higher. The environment is doing work on the system and the total mechanical energy of the system is lower.
