Study of conservation of generalized momentum as nonholonomic constraint;

In this paper, we have studied a generalized Hojman conserved quantity which results from the Mei symmetry of nonholonomic mechanical system with unilateral constraints in phase space.

Impact force calculation of viscous debris flow based momentum conservation;

From the theory of instantaneous expansion of detonation product and momentum conservation, this paper obtains velocity calculation model of explosively formed projectile(EFP)and the model is revised due to the influence of the ratio of charge altitude to charge diameter.

By adopting the momentum conservation theorem,perforation of truncated oval-nosed projectile into stiffened plates was investigated.

Simulating conservation of momentum in collision using 3dsMax8;

On conservation of momentum in elastic collision process;

This article proves the identity of two forms of rocket speed formula with the law of conservation of momentum and the limit of arithmetil progression in maths.

Special cases,such as conservation of momentum,conservation of angular momentum,and conservation of energy in quantum mechanics,are discussed.

Four examples,such as the sec- ond cosmic velocity and gravitational radius of black hole,the law of conservation of angular momentum and pul- sars,the magnetic flux and neutron star with strong magnetic field,the magnetic energy density and magnetar are presented.
