Yeah, and it's easier to teleport 100' than telekines 5lbs.
For telekinesis I allow speed to be swapped for weight. Allowing larger objects to be moved very slowly.
Makes sense actually, the telekinetic thing is a good house rule. . .sort of you apply 5# of force. . .takes a long time to move something big.
That said there's a limit to how much you can apply scientific logic to magic, at least in terms of "It would take more energy to teleport a 200 pound man 100 feet than pull a 5 pound object 100 feet over 1000 seconds."
Perhaps not in the magic logic. . .magic is almost intentionally contra scientific.
If you want to slap an energy budget on anything, creating a few pounds of something runs up against E=MC
2 in an ugly manner. . .like "Ahh, create meal for one man equals fireball that makes a smoking crater the size of kansas."
In the end, likely the answer boils back not to mystery of magic, but game balance relating to dropping heavy things on people, or flinging things very fast at people vs moving yourself or the willing around. . .but "mysteries of internal magic logic" sounds so much more poetic.
I do like the trading V for M logic of telekinesis, it doesn't even get overly dangerous.
Have you ever had anyone try firing light things like needles at high speeds at people?
