>swing with it be just equal or would it be greater
whats the metric?
it velocity then for a given power output during a swing the 20lbs axe will travel faster.

Your question needs to be worded better, but what I can pull from it, your asking whether a strong material object that is magically reduced to the same weight of another object will put a larger force behind it when accelerated by a barbarian.
Since Ek=.5mv^2, it doesn't matter what the material is made out of (Unless the thing you are hitting is relatively strong compared to the object), in the end, it all comes down to is how fast it is moving at time of impact and its weight.
Also please use SI Units (The units we use for the purposes of science) if you ever post here again.

it's magic, it could be whatever you want it to be

well, it was a theoretical question.

Assuming all things equal, will swinging a 10 lbs baseball bat at 1meter/second give off as much force as a 20lbs basebell bat at .5meter/second?

or is it an exponential thing when it comes to speed.

it depends on if the magic is physically changing the sword or if the enchantment effectively increases the strength of the barbarian so that he can swing a 90lb axe just as easily as he used to be able to swing a 20 lb axe

K = 1/2 mv^2

10*1^2 = 10
20*.5^2 = 5

speed matters

Well, the change in Momentum will be the same.
But the Kinetic Energy that the two items will possess will differ.

what's the scientific reason for a boxer's close range(clenched/point blank) punches to not do much damage as opposed to longer straights?

wouldn't it be at it's strongest in such a short range?

>serious replies

i'm not a scientist, nor a boxer, but i'd say that the strength in close range punches comes from the wrist or elbows, while longer straights use the whole arm + body weight, also there's more momentum and by extension, force/damage.

The punch is at its highest rate of speed at the end of a longer punch. That's why jabs are such an effective tactic in boxing. It allows to cause quick damage from a greater defensive distance/position

You say the wizard changes the weight of the axe - is that the mass of the axe, or just the gravitational pull exerted on it?

If the former, assuming adamantium is less than 4.5 times denser than iron, the angular momentum of the axe would be somewhat higher because of the larger size of the blade (unless the handle is shorter for the adamantium axe). This effect would be miniscule though, only about 5% more force into the swing - the main benefits would probably be in the adamantium's sharpness and resilience to damage, which would naturally remain unaffected by the change.

If, however, only the gravitational mass is affected, then the barbarian's swing will require and deliver almost the same amount of force as before. The only difference would be that because gravity doesn't have the same grasp on the axe, swinging the axe would feel very strange.
