i don't know a description bro :)
Term | Definition |
---|---|
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 |
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 |
