Moon's minimum fall damage

What does fall damage look like on the moon? Let's say 10 foot on earth sprains an ankle, 50 foot is lethal. Is it as simple as comparing moon's gravity to earth's or is there more maths involved?

There is no fall damage, if you jump too high you'll just float away into space.

Brainlet or just pretending?

Knowing that there's no air resistance, it'll all come down to impulse calculations. This is 1st year physics undergrad material, I might do it later if no one answers

40m or so would be reasonable without carrying much kit.
The average person can fall 3m relatively safely on Earth, beyond that risks injury exponentially.

Air resistance doesn't matter at all at these speeds.

No terminal velocity so you could potentially splatter real good.

OP asked for a generalization. Of course air resistance on earth wouldn't contribute much to falling from such heights, but as >>11745346
said, there's no speed limit, and in the end, the math is actually easier than that in Earth's case

Potential energy is linear and air resistance doesn't really factor into damage on Earth either at the scale we're talking about here. This is pretty easy, math-wise. Moon gravity at the surface is roughly a sixth of Earth gravity, so if you survive/get x damage from a fall on Earth you can just multiply the height by 6 to get the approximate same result on the Moon.
