11. Textile armor is tested for both penetration resistance by bullets and for the impact energy transmitted to the wearer. 12. Impact energy that does reach the'safety cell'is spread over as wide an area as possible to reduce its deformation.13. The test method attempted to simulate the capacity of a human attacker to deliver impact energy with their upper body. 14. Pennsylvania and West Virginia were selected because of the impact energy exploration could have on their economies, union officials said. 15. Modern safety barriers are designed to absorb impact energy and minimize the risk to the occupants of cars and bystanders. 16. The XC90's rear structure has been designed to absorb impact energy , with occupants are also protected by a whiplash protection system. 17. The flexibility of the system absorbs impact energy and dissipates it laterally, which reduces the forces transmitted to the vehicle occupants. 18. The flier disc loses impact energy at its sides to rarefaction waves, but a conical volume of explosive is efficiently shock compressed. 19. Impact energy is dissipated through deformation of the rail elements, posts, soil and vehicle bodywork, and friction between the rail and vehicle.20. The impact energy was equivalent to 3.5 kilotonnes of TNT; its trajectory was 269.8 degrees, with an impact angle of 45.4 degrees.
