In situations where general relativity can be approximated by linearized gravity, the deflection due to a spatially extended mass can be written simply as a vector sum over point masses.
42.
The first law states that if the net force ( the vector sum of all forces acting on an object ) is zero, then the velocity of the object is constant.
43.
As a scientist explained, the " weight " of Earth with respect to Earth is zero, since the vector sums of all the particles of Earth would cancel each other out.
44.
Complex power ( and its magnitude, Apparent power ) represents a combination of both real and reactive power, and therefore can be calculated by using the vector sum of these two components.
45.
Where is the vector sum of the physical forces applied to the particle and is the absolute acceleration ( that is, acceleration in an inertial frame ) of the particle, given by:
46.
Rotary wing aircraft and thrust vectoring V / STOL aircraft use engine thrust to support the weight of the aircraft, and vector sum of this thrust fore and aft to control forward speed.
47.
Ground speed can be determined by the vector sum of the aircraft's true airspeed and the current wind speed and direction; a headwind subtracts from the ground speed, while a tailwind adds to it.
48.
The impedance is the vector sum of resistance; it describes the phase difference and the ratio of amplitudes between sinusoidally varying voltage and sinusoidally varying current at a given frequency in an AC circuit.
49.
The peak horizontal ground acceleration ( PHA or PHGA ) can be reached by selecting the higher individual recording, taking the mean of the two values, or calculating a vector sum of the two components.
50.
Simplistically, the magnetic moment of the neutron can be viewed as resulting from the vector sum of the three quark magnetic moments, plus the orbital magnetic moments caused by the movement of the three charged quarks within the neutron.
