1. Impact energy is dissipated through redirection and deformation of the vehicle itself.2. Generally, at lower temperatures, the impact energy of a material is decreased. 3. A notched sample is generally used to determine impact energy and notch sensitivity. 4. Impact energy has been estimated at about 10 megatons.5. Climate change in California could also impact energy consumption. 6. Threat levels 1, 2 and 3 are based on impact energies of 24-, 33-and 43-joules respectively. 7. The backing plate reflects the impact energy back to the ceramic tile in a wider cone. 8. Using gravitational force, the height of the drop mass above the vest was proportional to the impact energy . 9. For safety, the Zephyr will have steel safety cage construction with engineered crush zones to absorb impact energy . 10. Nevertheless, the typical impact energies of the airsoft pellet tend to be much smaller than of the paintball.
