Cartesian z-axis basis unit vector unitless angular momentum: newton meter second (N⋅m⋅s or kg⋅m 2 ⋅s −1) inductance: henry (H) luminosity: watt (W) Lagrangian: joule (J) Lagrangian density: joule per cubic meter (J/m 3) length: meter (m) ℓ
atomic number (Z) The number of protons found in the nucleus of an atom. It is most often used to classify elements within the periodic table. atomic orbital atomic packing factor atomic physics A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A)
Exchange of a Z boson transfers momentum, spin, and energy, but leaves the interacting particles' quantum numbers unaffected – charge, flavor, baryon number, lepton number, etc. Because there is no transfer of electrical charge involved, exchange of Z particles is referred to as "neutral" in the phrase "neutral current".
Physics – branch of science that studies matter [9] and its motion through space and time, along with related concepts such as energy and force. [10] Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the ...

The physics convention. Spherical coordinates ( r , θ , φ ) as commonly used: ( ISO 80000-2:2019 ): radial distance r ( slant distance to origin), polar angle θ ( theta ) (angle with respect to positive polar axis), and azimuthal angle φ ( phi ) (angle of rotation from the initial meridian plane).
Police have confirmed a woman has been arrested amid the ongoing investigation into multiple babies suffering "unexplainable fractures" in 2023 and 2024 at the Henrico Doctors’ Hospital in Virginia
The fixed rate for a 15-year mortgage is 5.84%, down 12 basis points from last week's average 5.96%. These figures are lower than a year ago, when rates averaged 6.95% for a 30-year term and 6.38% ...
