# Measurements and Mathematics Terms

#### (mathematics is the deductive study of quantities, magnitudes, and shapes as determined by the use of numbers and symbols while every branch of science and engineering depends on mathematics; measurement is the process of associating numbers with physical quantities and phenomena and measurement is fundamental to the sciences; to engineering, construction, and other technical fields; and to almost all everyday activities)

The end points of a diameter are points on the circumference of the circle.

On earth, atmospheric pressure decreases with altitude and in its lowest layer, earth's atmosphere consists of nitrogen (78%) and oxygen (21%), both in molecular form (two atoms bonded together) and 1% argon.

Small quantities of other gases are important to the chemistry and physics of the earth's atmosphere, including water and carbon dioxide.

The earth's atmosphere is divided into four regions of atmosphere classified by temperature and the thermal structure of the earth's atmosphere is the result of the complex interaction of the following:

- Electromagnetic radiation from the sun.
- Radiation reflected from the earth's surface.
- Molecules and atoms in the atmosphere.

It is also commonly used to define any mathematical statement.

When forces balance each other they are said to be in equilibrium.

2. An Imperial unit of mass.

It is sometimes called the "long hundredweight" to distinguish it from the "short hundredweight", or cental, equal to 100 pound (45.4 kilogram)

It is opposite the right angle of the triangle.

2. A time lag in the occurrence of two associated phenomena, as between cause and effect.

3. A lagging or retardation of one of two associated phenomena or a failure to act in unison.
