Motion and Its Applications
All motion involves a change in the position of an object over time.
Motion can be described using mathematical relationships.
Many technologies that utilize the principles of motion have societal and environmental implications.
Mechanical Systems
Mechanical systems use force to do work.
The operation of mechanical systems can be described using mathematical relationships.
Friction is a force that influences the design, use, and effectiveness of mechanical systems.
Mechanical systems can be used to address social and environmental challenges.
Electricity and Magnetism
Relationships between electricity and magnetism are predictable.
Electricity and magnetism have many technological applications.
Technological applications that use electricity and magnetism can affect society and the environment in positive and negative ways.
Energy Transformations
Energy can be transformed from one type to another.
Systems that involve energy transformations are never 100% efficient.
Although technological applications that involve energy transformations can affect society and the environment in positive ways, they can also have negative effects, and therefore must be used responsibly.
Hydraulic and Pneumatic Systems
Fluids under pressure can be used to do work.
Fluids under pressure have predictable properties and many technological applications.
The uses of hydraulic and pneumatic systems can have social and economic consequences.
