In comics, Captain America's shield can absorb an incredible amount of kinetic energy from impacts (if not all of it) because of its vibranium makeup. That is why he can block hits from super-strong beings like Hulk without any damage done to him or him going backwards. But when he throws the shield it bounces off walls and other targets with little to no speed loss. I have two questions: 1. Is the shield's absorbing impact properties consistent or inconsistent with its minimal loss of speed when ricocheting? 2. Does the shield's ability to bounce off its targets with little to no speed loss make its force of impact very great (which is the very reason why Captain America can hurt very durable beings like Hulk with mere shield throws)?
