| Dec 5, 2023 at 19:12 | comment | added | Archisman Panigrahi | That's when you consider work done by external agents, and don't take the (conservative) gravitational force into account. Let's say, you don't know about the existence of gravity, and have done work $mgh$ on the system to raise it to a height $h$. But hey, you have done some work, then why didn't the kinetic energy increase? That's because you did not take the work done by the gravitational force into account, and you can deal with this by assuming the work you did went into some (fictitious) potential energy. | |
| Dec 5, 2023 at 19:09 | comment | added | Darth Vader | @ArchismanPanigrahi isn't the work done equal to change in total mechanical energy, which includes the increase in potential energy by $mgh$? | |
| Dec 5, 2023 at 19:06 | comment | added | Archisman Panigrahi | The total work done on the object is the change in its kinetic energy. What you obtained (net work done = 0) makes sense as the object was initially at rest, and is also at rest after raising it, and its kinetic energy does not change. | |
