In physical theories, a test particle, or test charge, is an idealized model of an object whose physical properties (usually mass, charge, or size) are...

Magnetic particle inspection (MPI) is a nondestructive testing process where a magnetic field is used for detecting surface, and shallow subsurface, discontinuities...

moving particle is different from non-relativistic mechanics. It is instructive to look at the total relativistic energy of a free test particle. An observer...

A point particle, ideal particle or point-like particle (often spelled pointlike particle) is an idealization of particles heavily used in physics. Its...

general relativity, Schwarzschild geodesics describe the motion of test particles in the gravitational field of a central fixed mass M , {\textstyle M...

The field around multiple particles is simply the vector sum of the fields around each individual particle. A test particle in such a field will experience...

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...

constitutes a single semantic unit consisting of a verb followed by a particle (e.g., turn down, run into, or sit up), sometimes collocated with a preposition...

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...

Higgs boson, sometimes called the Higgs particle, is an elementary particle in the Standard Model of particle physics produced by the quantum excitation...
