SCALAR- quantity, like distance, that has only a magnitude, or TEMPERATURE- measure of hotness of object on a quantitative
size. scale. In gases, proportional to average kinetic energy of
molecules.
SCIENTIFIC NOTATION - numbers expressed in form M * 10 ^ THERMAL ENERGY- internal energy. Sum of kinetic and
n , where 1< M < 10, and n is an integer.
potential energy of random motion of particles making up object.
SEMICONDUCTOR- material in which electrical conduction is THERMAL EQUILIBRIUM- is a state between two or more
smaller than that in a conductor, but more than in insulator. bodies where temperatures do not change.
SLOPE- ratio of the vertical separation, or rise to the horizontal THERMAL EXPANSION- increase of length or volume of object
separation, or run. due to change in temperature.
SPECTROSCOPE- device used to study spectrum of material.
THERMOMETER- is a device used to measure temperature.
SPECTRUM- collection of wavelengths in electromagnetic TIMBRE- sound quality or tone color; spectrum of sound
spectrum.
frequencies that produce a complete wave.
SPEED- ratio of distance traveled to time interval.
TONE COLOR-itimbre or tone quality.
SURFACE WAVE- wave on surface of liquid with characteristics TORQUE- iproduct of force and the lever arm.
of both longitudinal and transverse waves.
