1. Which organization or group of organizations is it the responsibility of to detect and track worrisome asteroids? I believe NASA and the USAF track such bodies if I'm not mistaken, but how many others are there? Who is "best" at it, or most relied-upon for spotting and cataloging them? 2...

Indeed! And my body is certainly less efficient than I'd prefer, but I'm only aiming for ballpark estimates, not precise figures, so my back-of-the-envelope math should suffice for my needs.

Of course! Thank you for the clarification, much appreciated!

Actually I have to confess, I'm gathering this information to work on a magic system for a TTRPG. I don't like the idea of "spell slots". The energy to use telekinesis and push someone back, for example, has to come from somewhere. I rather like the idea of spellcasters expending stores of body...

Ah yes, I agree. I suppose a human was not a good example, but I also only wanted a general idea of what it might take. Precision was not my goal, only to make sure I had a good enough understanding of what is happening with such an event. But I appreciate your thoughtful response nonetheless!

Ah, I think I understand it a bit better now. Thank you, this is very helpful.

Oooh, thank you! That is what I thought I was talking about. So actually this energy/effort amounts to a very puny morsel of a meal.

Excellent! Thank you for the corroboration. And if you would humor me once more, if I got the above correct then this should also be right: If I wanted to shove an adult human (let's say 70 kg) back about 5 meters, then... Work = 686 N * 5m 3,430 Joules of energy is required, or about 800~...

Hello all! First post here, and I apologize in advance if this question belongs elsewhere- I'll learn as I go. I am interested in knowing more about energy and performing work. In particular, if I have an object I would like to lift, how much energy I need to expend to do that. Take for...
