introduction to energy

how does work affect energy between objects so it can cause a change in the form of energy?
work transfers energy.
work changes energy.
work increases energy.
work decreases energy.

Explanation:

Work is the transfer of energy. When work is done on an object, energy is transferred to that object. For example, when you push a box (do work on it), you transfer energy to the box (it gains kinetic energy if it starts moving). Energy is conserved (the total amount of energy in a closed system remains the same), so work doesn't create or destroy energy, it just transfers it. It doesn't "change" energy in the sense of altering its fundamental nature (energy can change forms like from potential to kinetic, but work is the mechanism of transfer). It doesn't inherently "increase" or "decrease" energy (in a closed system, the total energy is constant, work just moves energy between objects or systems).

Answer:

Work transfers energy.
