The sum of the kinetic and potential energies of a system of objects is conserved: Group of answer choices only when no external force acts on the objects only when the objects move along closed paths only when the work done by the resultant external force is zero none of the above

Sagot :

The sum of the kinetic and potential energies of a system of objects is conserved only when no external force acts on the objects.

Conservation of mechanical energy

The principle of conservation of mechanical energy states that the total mechanical energy of an isolated system (absence of external force) is always constant.

M.A = P.E + K.E

where;

P.E is potential energy

K.E is kinetic energy

Thus, the sum of the kinetic and potential energies of a system of objects is conserved only when no external force acts on the objects.
