下面为大家整理的是以字母T开头的SAT2物理考试中常用词汇。掌握一定的物理词汇是备考SAT2的首要前提。所以，各位考生一定要多加重视词汇的积累，预祝各位考生考试成功。

Tail

In the graphical representation of vectors, the tail of the arrow is the blunt end (the end without a point).

Tangent

In a right triangle, the tangent of a given angle is the length of the side opposite the angle divided by the length of the side adjacent to the triangle.

Temperature

A measure of the average kinetic energy of the molecules in a system. Temperature is related to heat by the specific heat of a given substance.

Tension force

The force transmitted along a rope or cable.

Thermal energy

The energy of the molecules that make up an object. It is related to heat, which is the amount of energy transferred from one object to another object that is a different temperature.

Thermal equilibrium

Two materials are in thermal equilibrium if they are at the same temperature.

Third Law of Thermodynamics

An object cannot be cooled to absolute zero.

Threshold frequency

A property of a metal, the minimum frequency of electromagnetic radiation that is necessary to release photoelectrons from that metal.

Tip

In the graphical representation of vectors, the tip of the arrow is the pointy end.

Torque

The effect of force on rotational motion.

Total internal reflection

The phenomenon by which light traveling from a high n to a low n material will reflect from the optical interface if the incident angle is greater than the critical angle.

Transformer

A device made of two coils, which converts current of one voltage into current of another voltage. In a step-up transformer, the primary coil has fewer turns than the secondary, thus increasing the voltage. In a step-down transformer, the secondary coil has fewer turns than the primary, thus decreasing the voltage.

Translational kinetic energy

The energy of a particle moving in space. It is defined in s of a particle’s mass, m, and velocity, v, as (1/2)mv2.

Translational motion

The movement of a rigid body’s center of mass in space.

Transverse waves

Waves in which the medium moves in the direction perpendicular to the propagation of the wave. Waves on a stretched string, water waves, and electromagnetic waves are all examples of transverse waves.

Traveling waves

A wave with wave crests that propagate down the length of the medium, in contrast to stationary standing waves. The velocity at which a crest propagates is called the wave speed.

Trough

The points of maximum negative displacement along a wave. They are the opposite of wave crests.

以上就是关于SAT2物理考试常用词汇的全面内容，是以T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。
