How do you calculate the average jump height based on gravity and other forces?

Do you really need to know the air resistance though? Does it really make a significant difference in a jump? I would think I would struggle to jump even one centimeter higher in a vaccuum than I do normally.

I guess not, although it does make a certain difference depending on how high you jump.

I also heard that you could use this equation as well, if you leave out gravity:

H<SUB>x</SUB> = H<SUB>Earth </SUB>/ g<SUB>x</SUB>
<SUB></SUB>
<SUB></SUB>
H<SUB>x</SUB> = height you jump on planet x
H<SUB>Earth</SUB> = height you jump on Earth (obviously)
g<SUB>x</SUB> = the g-force on planet x
