Truly not trolling here. Mainly curious if a real answer for this has come up since it popped into my head the other day when reading something with cap in it.

FROM the wiki about the shield...
http://en.wikipedia.org/wiki/Captain_America%27s_shield

The vibranium in the shield grants it unusual properties, allowing it to absorb virtually all of the kinetic impact from any blows that the shield receives without injuring Rogers in the process.

If it absorbs kinetic energy, it should do it whether it is being hit or used to hit with, shouldn't it?

Ok, so the shield can absorb such ridiculous impacts without cap being thrown half way down the block when the hulk (or whatever) hits the shield he's holding because it's vibranium/ experimental iron alloy composition absorbs the impact.

Well if that's the case, shouldn't that same property also absorb the impact when things are the other way around and it hits something? GIven it's properties it shouldn't hit (or transfer the kinetic energy of a hit) all that hard/well at all... although this has never been the showing of it. I suppose this might extend to bouncing it off multiple objects as well as the first thing it hit should cause the shield to act as a dampener and absorb the kinetic energy of the throw, which would significantly lower it's speed and hitting power.

Anyway just curious if this has ever come up in conversation over here and if someone has come up with a suitable explanation why cap's shield seems to get to have it's cake and eat it too?




Not trolling, but rather a good question. I've wondered that myself.

Since the shield is truly unique -- one-of-a-kind -- one could imbue it with any property one wants, and who could question it? It could be argued that the almost magical properties of the shield are due to the vibranium/element X alloy it's made from. At one point, it was said to be made of an adamantium/vibranium alloy, but this was later refuted. Now, we don't really know what the other material is that makes up the shield.

Therefore, I will theorize that the shape of the shield is key: When a force, like a bullet or the Hulk's fist, hits the convex surface of the shield, it absorbs almost all the kinetic energy. However, when the shield hits something edge-on, due to the way the molecules are arranged, it almost has the opposite effect, losing very little momentum due to impacting a wall or a Hydra goon's skull-bone, and is able to ricochet all around their subterranean hideout.

Still, your point about it being used as an offensive weapon is a good one. Why, when Cap slams the convex side against Batroc's chest, doesn't it just feel to Batroc as an almost insignificant tap? Ya got me.
