1. The problem statement, all variables and given/known data When a gun fires a bullet why is the kinetic energy gained by the bullet much greater than the kinetic energy gained by the gun? 2. Relevant equations Kinetic Energy = 1/2 m v^2 3. The attempt at a solution Ok I release that Kinetic Energy depends on the square of the velocity so does this mean that the velocity is more important that the mass of the bullet/gun?
