Ans.
instead of work energy is the best word.
work or energy: ability of a person to some action.or u may say sum of k.e + p.e is a work.
and it is defined as w=f.s where f is a force and s us a displacement.
work is zero if f.s is zero.
work is positive if f.s is positive
and so on.
f.s=fscostheta
basically postve or negative work depends upon theata.
