Mach5: The total energy, angular and linear momentum of the universe are zero.

If all you want is a little linear momentum, the argument went, why not take it from the massive structures around you?

In special relativity, we must change the expression for linear momentum.

A parallel procedure applied to the conservation of linear momentum yields the three equations.

He established the principle that linear momentum is always preserved during hyperflight.

A running loop would have an extremely large amount of energy in the form of linear momentum.

If *all* the mass of the club were in the head, you could use either linear or angular momentum and get the same answer.

The waves can also carry off linear momentum, a possibility that has some interesting implications for astrophysics.

This is required to conserve linear momentum before and after the "collision".

This result means that linear momentum for the system is conserved.
