the test particle should not be attracted towards either stream.: 245–253  It is not at all clear that the forces exerted on the test particle are equal...

and an isotropic field exerts the same action regardless of how the test particle is oriented. Within mathematics, isotropy has a few different meanings:...

assumes that one of the inner binary's components, the secondary, is a test particle – an idealized point-like object with negligible mass compared to the...

test particles, the result of transporting spacetime vectors that can denote a particle's velocity (time-like vectors) will vary with the particle's trajectory;...

framework of the quantum field theory, even without referring to a test particle, a field occupies space, contains energy, and its presence precludes...

motion for a test particle in Kerr spacetime are integrable. Using these constants of motion, the trajectory equations for a test particle can be written...

\end{aligned}}} Given the Christoffel symbols, one can compute the geodesics of a test-particle. Instead of working in the holonomic basis, one can perform efficient...

The Treponema pallidum particle agglutination assay (also called TPPA test) is an indirect agglutination assay used for detection and titration of antibodies...

a test particle moves along a straight line at a constant speed. In the language of spacetime, this is equivalent to saying that such test particles move...

In performing a test, laboratory clinicians will mix a patient's cerebrospinal fluid, serum or urine with the coated latex particles in serial dilutions...

motion of particles suspended in a medium (a liquid or a gas). This motion pattern typically consists of random fluctuations in a particle's position inside...
