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

In the physical sciences, a particle (or corpuscule in older texts) is a small localized object which can be described by several physical or chemical...

the body's centroid; and orbital angular acceleration, involving a point particle and an external axis. Angular acceleration has physical dimensions of...

radians, the arc-length from the positive x-axis around the circle to the particle is ℓ = r ϕ {\displaystyle \ell =r\phi } , and the linear velocity is v...

In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. The Standard Model...

test particle is its electric charge and its mass. In this situation it is often referred to as a test charge. The electric field created by a point charge...

Wave–particle duality is the concept in quantum mechanics that quantum entities exhibit particle or wave properties according to the experimental circumstances...

often models real-world objects as point particles, that is, objects with negligible size. The motion of a point particle is determined by a small number...

L is the angular momentum vector and t is time. For the motion of a point particle, L = I ω , {\displaystyle \mathbf {L} =I{\boldsymbol {\omega }},} where...

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