11. The constant of integration, " h ", is the angular momentum per unit mass . 12. The figures given indicate what mass of water is required to dissolve a unit mass of compound indicated. 13. The flywheel material with the highest specific tensile strength will yield the highest energy storage per unit mass . 14. Parts of this diagram represent distances, other parts gravitational accelerations ( attractive forces per unit mass ). 15. This results in a greater payload to fuel ratio which reduces the cost per unit mass to orbit. 16. You would significantly decrease the propulsion system effectiveness per unit mass if you split it up that way. 17. It also has the best energy content per unit mass of any fuel and is a light molecule. 18. On a per unit mass basis, Boron outperforms hydrocarbon fuels but is not as good as hydrogen. 19. For example proper velocity equals momentum per unit mass at any speed, and therefore has no upper limit. 20. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle.
