It would depend on the directions of the boxes, but I believe there would be 3 units of work.
The substance has melted
ex: ice+heat= water
Answer:
Water in an artificial lake held behind a dam
Explanation:
Potential energy is energy that can be converted to kinetic energy, for example, an object at a certain height has potential energy because we can drop the object to have kinetic energy.
Therefore, the best example of potential energy is water in an artificial lake held behind a dam because without the dam, the water will start to move and it becomes the energy into kinetic energy.
The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it whereas mass is the amount of matter contained in a body. The SI unit of weight is Newton whereas the SI unit of mass is Kilogram.
No idea about weightless maybe the objects not apparently acted on by gravity.
