well.. for my sceicne fair expiriment, i'm finding whether the counterweight on a trebuchet affects how much power the projectile flies with.
i'm testing this by launching projectiles filled with water and they break when they hit the ground. then, i measure the length of the water to see how much power it had..
only problem is, i gotta prove taht the longer the water travels, the more force it has...
lol..if that didnt makes sense, just think of it this way :
I need a way to prove that the longer mark a projectile leaves, the more power it has...
(ps, anyone have some other word besides "power" that i can use to make it more science-related)

i was wondering if there was some kinda law like
"the law of energy" or something like that. so i dont have to do all this stuff to prove it

work=forceXdistance
jules=newtonsXmeters
power=work/time
watts=jules/seconds
don't worry about using the term "power" because it's really a technical term.

Why not just make it simple and determine how far an object flies? Then your hypothesis can be that the counterwight effects the distance of the projectile. Remember, It's important to make sure your projectile's size and weight remain constant. Hop ethis helps.
