CALORIE- A unit of heat and energy equal to the amount of
energy requires to raise the temperature of 1 gram of water by
1° Celsius.
CALORIMETRY- is a method of measuring the heat transfer
within a chemical reaction or other physical processes, such as
a change between different states of matter.
CENTER OF MASS- is a position defined relative to an object or
system of objects. It is the average position of all the parts of
the system, weighted according to their masses.
CHARLES'S LAW- gives the relationship between the volume
and the temperature of a fixed mass of gas at constant pressure.
COMPRESSIVE FORCE- occurs when a physical force presses
inward on an object, causing it to become compacted.
CONDENSATION- is the change of the physical state of matter
from the gas phase into the liquid phase, and is the reverse of
vaporization.
CONVECTION- process by which heat is transferred by
movement of a heated fluid such as air or water.
CONVERSION- a change between different units of
measurement for the same quantity.
DAMPING- in physics, restraining of vibratory motion, such as
mechanical oscillations, noise, and alternating electric
currents, by dissipation of energy.
DECIBEL- unit for expressing the ratio between two physical
quantities, usually amounts of acoustic or electric power, or for
measuring the relative loudness of sounds.
DENSITY- is the mass per unit volume of any object. It is
calculated by dividing the mass of an object by its volume.
DIESEL ENGINE- also known as the compression-ignition
engine, is a heat engine that runs off of the energy provided by
the combustion of diesel fuel under high pressure and
temperature.
DISPLACEMNENT- is a vector quantity that refers to "how far
out of place an object is"; it is the object's overall change in
position.
DOPPLER EFFECT- refers to the change in wave frequency
during the relative motion between a wave source and its
observer.
DOPPLER SHIFT- This change in observed wavelength, or
frequency, is known as the Doppler shift.
