Final answer:
The work done on pulling a heavy box can result in it gaining kinetic energy, and also in increased thermal energy due to friction. Potential energy and chemical energy are not the main forms involved here, unless the box's elevation or chemical structure is changed.
Step-by-step explanation:
When a heavy box is pulled along the floor with a work done of 200 J, the energy that is imparted to the box can take several forms. The final form of the energy store will depend on the nature of the interaction between the box and the floor. If the box is accelerating and moving, some of this work will be converted into kinetic energy which is the energy of motion. However, it is likely that not all of the work done on the box will go into kinetic energy. Some of this energy will be transformed into thermal energy due to friction between the box and the floor. The thermal energy is essentially the heat produced by the friction, and in real-world scenarios, this is where a significant portion of the energy might go. There is no indication in the scenario that the box is being lifted in a way that would increase its potential energy, and since we are not involving biochemical processes here, chemical energy is not the correct form either. Therefore, while some work may translate into kinetic energy, it is equally important to consider the transformation into thermal energy due to frictional forces.
