These vector quantities point in the direction of the relative motion of the lens with respect to the source.
12.
Remember, momentum is a vector quantity and if you add up those vectors the result doesn't change.
13.
First it is related to the 4-current "'J "', a vector quantity given by
14.
A torque caused by a force \ scriptstyle \ vec F is a vector quantity defined with respect to some reference point:
15.
For transport phenomena, flux is a vector quantity, describing the magnitude and direction of the flow of a substance or property.
16.
Like linear momentum, angular momentum is vector quantity, and its conservation implies that the direction of the spin axis tends to remain unchanged.
17.
:Wavenumber, " k ", is the spatial frequency analogue of angular temporal frequency and is measured in radians per vector quantity.
18.
A dipole is characterized by its dipole moment, a vector quantity shown in the figure as the blue arrow labeled " M ".
19.
This is because dipole moments are euclidean vector quantities with magnitude and direction, and a two equal vectors who oppose each other will cancel out.
20.
Average velocity is a vector quantity and is net displacement divided by time, and can be zero if you return to the start ."
