SAT2物理考试需要大家在备考的时候记忆大量的专业词汇，这样才能更快更好的解答相关题目。下面一诺留学为大家搜集整理了SAT2考试物理专业词汇汇总(字母W开关)，希望能够帮助大家更好地备考SAT2物理考试。

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.
