Energy forces doing work
WebWhen a friction force does work on an object , the total mechanical energy of that object is changed. The total mechanical energy of an object remains constant if the only forces doing work on the object are conservative forces. If an object gains mechanical energy, then one can be certain that a non-conservative force is doing work. WebNuclear binding energy in an atom is a concept in experimental physics is the minimum energy that is required to disassemble the nucleus of an atom into its constituent protons and neutrons, known collectively as nucleons.The binding energy for stable nuclei is always a positive number, as the nucleus must gain energy for the nucleons to move apart from …
