This document provides an overview of engineering, including its impacts and importance to society, core characteristics, practical applications, theories used, phenomena explored, and how data is collected and researched. Engineering helps make human life better by improving efficiency and advancing technology. It is logical, precise, creative, analytical, and responsible. Practical applications include constructing, designing, programming, analyzing, and testing. Theories of motion, energy, and thermodynamics are applied. Safety innovations in transportation show the impacts of engineering over time. Data collection methods and concerns about accuracy and ethics are also discussed.

5. Theories Used In Engineering
 F=ma
 V=IR
 P=(I^2)R
 First law of thermodynamics: The increase in internal
energy of a closed system is equal to the difference of the
heat supplied to the system and the work done by it.
 Zeroith law of thermodynamics: If two systems are each in
thermal equilibrium with a third, they are also in thermal
equilibrium with each other.
 Law of conservation of energy: Energy cannot be created
or destroyed, but it can be converted from one state to
another.

15. Ethical Concerns
 We must be accurate
and confirm that our
designs have no
flaws in order to
ensure we do not
bring harm upon
anyone.
 Ecological and
economical effects.
