I don't know much yet about energy and work, as I've only had one lesson on it so far. However, our teacher told us that zero work is confusing and that we wouldn't need to know about it (with the virus and all, most units have been cut short so unnecessary things are glossed over).
Nonetheless, I still want to understand what zero work is. Which brings me to my question: From my understanding, work is equal to the force net of an object multiplied by the distance covered. In terminal velocity, the net force of an object would be 0 because the air resistance or drag of the object cancels out the force of gravity. Therefore, the product of force net and the distance covered of an object in terminal velocity would be zero. Which is why my understanding is that terminal velocity would be an example of zero work.
Apparently, my teacher isn't so sure that it is, so that brought me here. Can anyone clear up this misunderstanding, or confirm my idea?
