weak interaction Also weak force or weak nuclear force. One of the four fundamental forces of nature, along with the strong nuclear force, electromagnetism, and gravitation. It is responsible for the radioactive decay of subatomic particles and initiates the process known as hydrogen fusion in stars.
weber (Wb)
wedge A triangular round tool in the form of a compound and portable inclined plane; one of six classical simple machines.
weight
wheel and axle A wheel attached to an axle in such a way that the two parts rotate together and transfer forces between them; one of six classical simple machines.
white body A hypothetical idealized physical body that reflects all incident electromagnetic radiation completely and uniformly in all directions; the opposite of a black body.
wind The flow of gases on a large scale.

work function
== X ==
X-ray A high-energy photon (between 100 eV and 100 keV) with a wavelength shorter than that of ultraviolet radiation and longer than that of gamma radiation.
== Y ==
Young’s modulus A measure of the stiffness of a solid material which defines the relationship between mechanical stress and strain.
== Z ==
Zeeman effect The effect of splitting a spectral line into several components in the presence of a static magnetic field by the lifting of degeneracy in electronic states.
