[QUOTE="WildcatB, post: 202473, member: 10379"] JWP475 he's not wrong. If Momentum is transferring, so is Kinetic Energy. You can't have one without the other and there is a positive relationship between them. That means that as one grows so does the other. Here are the equations: Momentum = Mass x Velocity Kinetic Energy = (1/2)Mass x Velocity^2 Notice that you can't have one without the other. Each is defined in terms of the same variables - Mass and Velocity. When the author of your book said that energy is not a factor in a kill, something got lost in translation. I'm sure he meant to say that energy is not the ONLY factor in a kill. There are many variables that go into a kill - too many to actually quantify in an [B]absolute[/B] way.However, to say that energy in NOT a factor in a kill is just as wrong as saying that energy is the ONLY factor in a kill. Yes in an inelastic collision, it is said that kinetic energy is not conserved because SOME of the energy is converted to internal energy in one or more of the bodies. The important word in that sentence is [B]SOME[/B]. That means [B]NOT ALL[/B]. You’ve miss-read your book by thinking that ALL or even MOST of the kinetic energy from a bullet is converted into thermal energy. If that were the case, there would be no energy left to be provide momentum. Because even though kinetic energy is not conserved as kinetic energy, total energy is. [/QUOTE]
