For Studying.

TermDefinition
Technology: The modification of the natural environment in order to satisfy human needs and wants.
Technology Literacy: The ability to use, manage, understand, and access technology.
Materials Technology: The technology of producing, altering, and combining materials.
Transportation Technology: The technology of transporting people and goods.
Information & Communication Technology: The technology of communicating to people and machines.
Medical Technology: The technology of caring for the sick and curing disease.
Agricultural & Bio Technology: The technology of farming and DNA.
Construction Technology: The technology of building and maintaining structures.
Energy & Power Technology: The technology of producing and transferring energy into work/power.
Manufacturing Technology: The technology of producing goods in a factory.
Science: The knowledge of the natural world (Discovery). Helps us develop technology.
Invention: A totally new product, produced from ideas and imagination.
Innovation: An improvement to an invention. You will have more innovations than inventions.
Positive Outcomes vs. Negative Outcomes: Positive: technology solves problems, Negative: creates new problems
Systems Model: A group of units/parts that work together. Consists of input, process, output and sometimes feedback.
Open-Loop System: A system in which there is no feedback. Input>Process>Output
Closed-Loop System: A system in which there is feedback. Input>Process>Output>Feedback
Systems Thinking: Viewing problems as parts of an overall system. What component is causing the problem?
Controls: Mechanisms or steps that are performed using information about the system that cause the system to change.
Input: Anything put in to a system. Can be capital ($), raw materials, people (labor), fuel, etc.
Process: The process of changing/using the inputs. Ex. The burning of the fuel to produce power/work in an engine.
Output: The results of the system. Can be power, movement, a product, etc.
Feedback: Information about the system that can be used to alter the system. Can be a gauge or other measurements.
Criteria: The problem you are trying to solve/the goal of your design. Example: Design a bridge.
Constraint: Limitations to your design. You may have a time limit, money limit or specifications for the appearance.
Prototype: A full-scale working model of the product. For example the crash car used to test car safety.
Newton’s 1st Law: An object remains still or remains in motion unless acted upon by an outside force.
Newton’s 2nd Law: Force = mass x acceleration. The greater the mass, the more force that is needed to move it
Newton’s 3rd Law: For every action, there is an equal and opposite reaction.
Mechanical Advantage: A force that is increased by the use of a machine. Ex. using a drill to drive a screw.
