Wave

A system with many parts in periodic, or repetitive, motion. The oscillations in one part cause vibrations in nearby parts.

Wave speed

The speed at which a wave crest or trough propagates. Note that this is not the speed at which the actual medium (like the stretched string or the air particles) moves.

Wavelength

The distance between successive wave crests, or troughs. Wavelength is measured in meters and is related to frequency and wave speed by = v/f.

Weak nuclear force

The force involved in beta decay that changes a proton to a neutron and releases an electron and a neutrino.

Weber

The unit of magnetic flux, equal to one T · m2.

Weight

The gravitational force exerted on a given mass.

Weightlessness

The experience of being in free fall. If you are in a satellite, elevator, or other free-falling object, then you have a weight of zero Newtons relative to that object.

Work

Done when energy is transferred by a force. The work done by a force F in displacing an object by s is W = F · s.

Work function

The amount of energy that metal must absorb before it can release a photoelectron from the metal.

Work-energy theorem

States that the net work done on an object is equal to the object’s change in kinetic energy.

Zeroth Law of Thermodynamics

If two systems, A and B, are in thermal equilibrium and if B and C are also in thermal equilibrium, then systems A and C are necessarily in thermal equilibrium

以上就是关于SAT2物理考试核心词汇的全面内容，是以W-Z开头的。各位考生可以作为备考时的参考资料，希望对各位考生的SAT2考试有所帮助。
