　　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 fect of force on rotational motion.

　　Total internal rlection

　　The phenomenon by which light traveling from a high n to a low n material will rlect 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 dined 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.

　　小编提醒：单词的记忆要靠长期的坚持，考生们一定要持之以恒，每天都拿出来看一看背一背，让这些词汇在大脑中形成长期记忆，这样就不会轻易地忘记背过的词汇了。
