(for more about Power Words, click here)

air pressure     The force exerted by the weight of air molecules.

coil     Concentric rings or spirals formed by winding wire or some other fiber around and around a core; or the shape that such a wire would make.

colleague     Someone who works with another; a co-worker or team member.

current     (in electricity) The flow of electricity or the amount of charge moving through some material over a particular period of time.

electric current     A flow of electric charge — electricity — usually from the movement of negatively charged particles, called electrons.

electricity     A flow of charge, usually from the movement of negatively charged particles, called electrons.

engineer     A person who uses science to solve problems. As a verb, to engineer means to design a device, material or process that will solve some problem or unmet need.

fabric     Any flexible material that is woven, knitted or can be fused into a sheet by heat.

feedback     A response or assessment that follows some a particular act or decision. Or a process or combination of processes that propel or exaggerate a change in some direction. For instance, as the cover of Arctic ice disappears with global warming, less of the sun’s warming energy will be reflected back into space. This will serve to increase the rate of Earth’s warming. That warming might trigger some feedback (like sea-ice melting) that fosters additional warming.

monitor     To test, sample or watch something, especially on a regular or ongoing basis.

nickel     Number 28 on the periodic table of elements, this hard, silvery element resists oxidation and corrosion. That makes it a good coating for many other elements or for use in multi-metal alloys.

online     (n.) On the internet. (adj.) A term for what can be found or accessed on the internet.

polymer     A substance made from long chains of repeating groups of atoms. Manufactured polymers include nylon, polyvinyl chloride (better known as PVC) and many types of plastics. Natural polymers include rubber, silk and cellulose (found in plants and used to make paper, for example).

pressure     Force applied uniformly over a surface, measured as force per unit of area.

robot     A machine that can sense its environment, process information and respond with specific actions. Some robots can act without any human input, while others are guided by a human.

roboticist     Someone who designs or builds robots.

tactile     An adjective that describes something that is or can be sensed by touching.

virtual reality     A three-dimensional simulation of the real world that seems very realistic and allows people to interact with it. To do so, people usually wear a special helmet or glasses with sensors.
