$----------$

only the potential energy does the work

the system does work on the environment

the mechanical energy does not change

the change in potential energy may be greater as well as less than the work the system does on the environment

the body cannot do more work than the change of its potential energy

The change in kinetic energy is Blank because Blank.target $1$ of $2$target $2$ of $2$
