acceleration: A change in the speed or direction of an object.
average: Term (in science) for arithmetic mean. The sum of a number group divided by the size of the group.
concrete: Be solid and genuine. (under construction) A simple two-part building material. Some are made of sand or crushed rock chips. The other is made of cement, which hardens and helps bind the particles of material together.
Maintenance: The act of preserving or protecting something. The focus of this work ranges from fine art to endangered species and other aspects of the natural environment.
data: Facts and/or statistics collected together for analysis. They are not necessarily organized in a way that gives them meaning. For digital information (the type stored by computers), these data are typically numbers stored in binary code and represented as strings of 0’s and 1’s.
environment: The sum of everything that exists around an organism, or the processes and conditions produced by those things. Environment can also refer to the weather or ecosystem in which an animal lives, or the temperature and humidity (or the placement of things near the item of interest).
equation: In mathematics, a statement that two quantities are equal. In geometry, equations are often used to determine the shape of curves and surfaces.
element: Something that plays a role in a particular state or event. Contributor.
Power: external influences that can change the motion of objects, move objects closer together, or cause motions or stresses in stationary objects.
information: (as opposed to data) A fact provided or a learned trend about something or someone, often as a result of the study of data.
infrared: A type of electromagnetic radiation that is invisible to the human eye. The name borrows from Latin and means “under the red.” Infrared light has wavelengths longer than those visible to the human eye. Other invisible wavelengths include X-rays, radio waves, and microwaves. Infrared light tends to record the thermal signature of objects and environments.
Physical energy: Energy retained by an object because it is in motion. The amount of this energy involved depends on both the object’s mass (usually its weight) and its speed.
laser: A device that produces an intense beam of coherent light of a single color. Lasers are used for drilling and cutting, alignment and guidance, data storage, and surgery.
mass: A number that indicates how much an object resists acceleration and deceleration. Basically, it is a measure of how much material an object is made of.
Physics: Scientific study of the nature and properties of matter and energy. Classical physics explains the nature and properties of matter and energy based on descriptions such as Newton’s laws of motion. Quantum physics, a field of study that emerged later, is a way to more precisely describe the motion and behavior of matter. Scientists who work in such fields are known as physicists.
potential energy: The energy that an object retains due to its position or condition (such as being held still by a brake or suspended by a wire) rather than by its movement. Examples of objects with this type of energy include a compressed spring or a mass of snow on a hillside (think of its ability to cause an avalanche).
range: the total extent or distribution of something. For example, a plant or animal’s habitat is the area in which it naturally occurs. (in mathematics or measurement) a range over which a value varies (such as from the highest temperature to the lowest temperature). Also, the distance something can reach or be perceived.
Sun: The star at the center of Earth’s solar system. It is located approximately 27,000 light years from the center of the Milky Way galaxy. It is also a word that refers to a star like the sun.
variety: (in agriculture) A term given by plant scientists to different varieties (subspecies) of plants that have desirable traits. When plants are intentionally bred, they are called cultivars or cultivars.
wood: A porous, fibrous structural tissue found in the stems and roots of trees, shrubs, and other woody plants.
