Jumping and Falling Rules - need help!

My Nexus D20 system uses a scale system that charts the size of objects versus their toughness and strength.
Nexus Scale - Nexus D20 Wiki

I'm trying to come up with some logical jumping and falling rules based on this system. Obviously most creatures can jump the length of their body. Some creatures can jump much better then that. A creature that is the size of a dinosaur wouldn't notice falling 10 feet if they are 40 ft tall. However a person falling 10 ft would notice that.
I was thinking of putting in a trait that just says if the creature is light, moderate, or heavy for their strength to reflect this to some degree. This way I could have a medium strong creature like a dwarf be heavy and a medium strong creature like a minor vampire that is light and is more likely to be able to jump farther for their extra strength.

How can I generate a realistic jumping and falling system based on this?

A universal scale is a neat idea but your conception of the physics is incorrect. Push an elephant off a 10' cliff and it will not only notice it, it will break its legs. A man will drop off a 10' cliff and usually walk away; he might twist his ankle if he lands badly. A spider that drops 10' won't notice at all because the spider's velocity through the air will be a lot lower because it's not much more dense than the air through which it falls, so it won't fall fast. A cat thinks of a 10' drop the way you or I think of a step.

It's a lot more complicated than a single scalar variable can encompass, is what I'm getting at.

hmmm
well the other idea I had was some sort of Leaping ability that creatures I would think would be able to leap would have.
