Energy cannot be created or destroyed, it can be converted from one form to another Thermal- Heat, the vibration and movement of the atoms and molecules within substances
Radiant- Light, electromagnetic energy that travels in transverse waves
Electrical- Energy made available by the flow of electric charge through a conductor
Mechanical- Energy stored in the movement of objects
Chemical- In the bonds of atoms and molecules
Nuclear- In the nucleus of an atom, the energy that holds the nucleus together Energy Types Thermodynamics Power Plants Generate electricity from various
energy resources Renewable
Solar
Wind
Water Non- Renewable
Fossil Fuels
Uranium Power Systems Source of Energy

For Example, style, shape, color, materials, etc. The Engineering Design Process 1.Define a Problem
2.Brainstorm Possible Solutions
3.Generate Ideas
4.Research Ideas and Explore Possibilities
5.Specify and Identify Criteria
6.Consider Alternative Solutions
7.Select An Approach
8.Develop a Written Design Proposal
9.Make a Model or Prototype
10.Test and Evaluate the Design Using Specifications
11.Refine/ Create the Design
12.Communicate Results and Processes Scientific Method vs. Engineering Scientific Method is a Define Linear Procedure Criteria The desired elements and features of a product or system What the design is supposed to do, related to function, aesthetics Constraints Limitations on a Design Involves time, budget, and safety among other constraints Modeling During design process, check for proper design to note areas of needed improvements Conceptual, Physical, and Mathematical Models You want to model everything that is similar to the real thing Communication Engineers and Designers communicate with different audiences:
Clients
Manufacturing Companies
Government Agencies
