Alright, so in Pathfinder (like Dungeons and Dragons) there's a spell that allows you to lift/move stuff within 25 ft with 5 pounds of force.
A dagger weighs 1 pound [a rapier 2 pounds, a star dagger weighs 3 pounds]. I assume the remaining [2-]4 pounds of force wouldn't be enough to stab for significant damage. However, if the object is lifted and then released above the enemy that might work.
1. Damage
a. How much force does a 1 pound object falling 25 feet deliver assuming normal gravity? (would be nice if you show the math so I can repeat it with different weights)
b. I haven't yet found out the surface area of a dagger tip, but if it was known, and I combined it with the result from a. to get X (force/square inch for dagger falling), and then compared it to Y (the force/quare inch necessary to penetrate bone/skull), how much would X have to be larger than Y to penetrate? If the two were exactly the same would it just penetrate or just not?
2. Speed
if the object weighs 1 pound, and it's pulled upwards with 5 pounds of force, how fast is it being lifted? - My first idea was that it would be the same question as 1.a. except with 4 pounds and in the opposite direction, but heavier doesn't fall faster, only stronger, right?
I just imagined a powerful crane slowly lifting a feather, as it's designed for moving heavier things... Then I imagined me being in the gym trying to lift 80 pounds quickly (almost throwing) instead of steadily/with proper technique. For some things that makes it easier (cheating yourself), for other's (say straight up) it's a bad idea because at the tip of the lift movement for a moment it'll feel like it's falling, as in weighs even more than it's full weight. I assume because of heavy things that aren't in motion wanting to stay not in motion, trying to "convince" them faster would take stronger force... - Is there a maximum speed that 1 pound object can be lifted at using 5 pounds of force?
I'm excited to hear your thoughts, and thanks a lot

P.S. if you don't like the idea of trying to kill mean orks in a game, then replace dagger with metal ball, and assume I'm trying to trigger a pressure plate trap (so my people don't run in) that requires a certain amount of force/square inch to be activated. ;-)
