According to Noether's theorem, space translational symmetry of a physical system is equivalent to the momentum conservation law.

Because of momentum conservation laws, the creation of a pair of fermions (matter particles) out of a single photon cannot occur.

It also holds in special relativity (with a modified formula) and, with appropriate definitions, a (generalized) linear momentum conservation law holds in electrodynamics, quantum mechanics, quantum field theory, and general relativity.

The reasoning behind that is that a pair of electron and hole near minima of their bands in an indirect gap semiconductor can recombine only with production of a phonon and a photon, due to energy and momentum conservation laws.

In this form, MOND is not a complete theory: for instance, it violates the law of momentum conservation.

Nothing like that was happening, which suggested that, again, the normal laws of momentum conservation were being suppressed, or ignored, or put on hold until some later reckoning.

Illustrates the laws of conservation of momentum and energy.

It couldn't repeal the law of conservation of momentum.

It defies the law of conservation of momentum as we know it.

The law of conservation of momentum requires that active and passive gravitational mass be identical.

Their design principles are not supported by prevailing scientific theories, and they apparently violate the law of conservation of momentum.

This fact, known as the law of conservation of momentum, is implied by Newton's laws of motion.

By itself, the law of conservation of momentum is not enough to determine the motion of particles after a collision.

Derive the law of conservation of momentum for an isolated system consisting of two interacting particles.

The recoil of a firearm, whether large or small, is a result of the law of conservation of momentum.

He noted that energy conservation holds in both frames, but that the law of conservation of momentum is violated.

It follows from the law of conservation of momentum that this "knockback" can never exceed the recoil felt by the shooter.

But the law of conservation of momentum states that the magnitudes of their momenta must be equal:

Recoil is explained by the law of conservation of momentum, and so it is easier to discuss it separately from energy.

By the law of conservation of momentum, the wind moves the sail as the sail redirects downwash air backwards.

Any apparently reactionless drive is treated with skepticism by the physics community, since a truly reactionless drive would violate the law of conservation of momentum.

- Students are introduced to the Law of Conservation of Momentum, and will use this to study one and two-dimensional collision systems that require vector analysis.

It has unified the laws of conservation of momentum and of energy into one single law and has demonstrated the equivalence of mass and energy.

In 1936, working with Alikhanian and L. A. Artsimovich, he experimentally corroborated the law of conservation of momentum in pair annihilation.

It has been observed that, in any collision, the vector sum of the momenta of all interacting particles always remains constant: hence the law of conservation of momentum.

This backward momentum is equal in magnitude, by the law of conservation of momentum, to the forward momentum of the ejecta (projectile(s), wad, propellant gases, etc..

In Newtonian mechanics, the law of conservation of momentum can be derived from the law of action and reaction, which states that every force has a reciprocating equal and opposite force.

The law of conservation of momentum means that in order for a propulsion method to change the momentum of a space craft it must change the momentum of something else as well.

At first, this might seem to violate the law of conservation of momentum, but such an interaction is seen to conserve momentum if the momentum of electromagnetic fields is taken into account.

The law of conservation of momentum is usually taken to imply that any engine which uses no reaction mass cannot accelerate the center of mass of a spaceship (changing orientation, on the other hand, is possible).

In order to work out the distribution of kinetic energy between the firearm and the bullet, it is necessary to use the law of conservation of momentum in combination with the law of conservation of energy.
