So, we were all watching the Captain America movie the other night. And in the movie Captain America gets a shield made out of vibranium, an alien metal that magically absorbs the energy from impacts. He tests it by getting shot at. So he’s got this great defensive shield that will protect him. But then later in the movie he uses it as a weapon by throwing it at some bad guy. Here’s my question. How does that work? Wouldn’t the shield absorb the impact once it hit the other guy, thereby rendering it useless as a weapon?
My husband was annoyed by my questioning the abilities of a superhero. (A superhero who, by the way, grew like six inches and put on 60 pounds with no caloric input, morning sickness, or apparent stretch marks).
Physics. How does it work?
