The Lorentz force, on the other hand, is a physical effect that occurs in the vicinity of electrically neutral, current-carrying conductors causing moving electrical charges to experience a magnetic force. The Lorentz force law states that a particle of charge q moving with a velocity v in an electric field E and a magnetic field B experiences ...
Positive inclination is northward, while negative inclination is southward. The longitude of the ascending node Ω, measured in the fundamental plane counter-clockwise looking southward, from a reference direction (usually the vernal equinox) to the line where the spacecraft crosses this plane from south to north. (If inclination is zero, this ...
The impulse delivered by a varying force is the integral of the force F with respect to time: =. The SI unit of impulse is the newton second (N⋅s), and the dimensionally equivalent unit of momentum is the kilogram metre per second (kg⋅m/s).
A sideslip develops, resulting in a slip-flow which is right-to-left. Now examine the resulting forces one at a time, calling any rightward influence yaw-in, leftward yaw-out, or roll-in or -out, whichever applies. The slip-flow will: push the fin, rudder, and other side areas aft of the plane's centre of gravity to the left, causing a right ...
Specific impulse (usually abbreviated I sp) is a measure of how effectively a rocket uses propellant or jet engine uses fuel. By definition, it is the total impulse (or change in momentum) delivered per unit of propellant consumed [4] and is dimensionally equivalent to the generated thrust divided by the propellant mass flow rate or weight flow rate. [5]
The jet force can be divided into components. The "forward" component of this force is generally referred to as thrust. [1] The upward component of jet force is referred to as lift. [2] There are also two other forces that impact motion of aircraft. Drag, which is also referred to as air resistance, is the force that opposes motion. As such, it ...

The plane perpendicular to the axis of angular momentum and passing through the center of mass [18] is sometimes called the invariable plane, because the direction of the axis remains fixed if only the interactions of the bodies within the system, free from outside influences, are considered. [19]
