specific momentum
1Specific impulse — (usually abbreviated I sp) is a way to describe the efficiency of rocket and jet engines. It represents the impulse (change in momentum) per unit of propellant. The higher the specific impulse, the less propellant is needed to gain a given amount …
2Momentum exchange tether — Momentum Exchange Tethers is one of many applications for space tethers. This sub set represents an entire area of research using a spinning conductive and/or non conductive tether to throw spacecraft up or down in orbit (like a sling), thereby… …
3Specific heat capacity — Specific heat capacity, also known simply as specific heat, is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by a certain temperature interval. The term originated primarily through the work …
4Specific orbital energy — In the gravitational two body problem, the specific orbital energy (or vis viva energy) of two orbiting bodies is the constant sum of their mutual potential energy ( ) and their total kinetic energy ( ), divided by the reduced mass. According to… …
5Specific relative angular momentum — In astrodynamics, the specific relative angular momentum of an orbiting body with respect to a central body is the relative angular momentum of the first body per unit mass. Specific relative angular momentum plays a pivotal role in definition of …
6Momentum Deferred — Fringe episode …
7Momentum operator — See also: Momentum In quantum mechanics, momentum is defined as an operator on the wave function. The Heisenberg uncertainty principle defines limits on how accurately the momentum and position of a single observable system can be known at once.… …
8Angular momentum — For a generally accessible and less technical introduction to the topic, see Introduction to angular momentum. Classical mechanics Newton s Second Law …
9Relative angular momentum — In astrodynamics, the relative angular momentum (mathbf{H 2}/{1},!) of an orbiting body (m 2,!) relative to a central body (m 1,!) is the moment of (m 2,!) s relative linear momentum::mathbf{H 2}/{1}=mathbf{r} imes m 2mathbf{v},!where: *mathbf{r} …
