system
Systems that rely on physical parts to accomplish a task are called what?
Physical Systems
______ go into a system, such as energy, raw materials, or forces
Inputs
This is a basic system that makes work easier.
What is a simple machine?
This is the ability to do work (moving something against a force).
What is energy?
The parts included in a system are called what?
Components
The digestive, circulatory, and nervous systems are examples of this type of physical system.
What are natural physical systems?
______ are the things or services that a system produces.
Outputs
This is the ability to do something without wasting energy, effort, or raw materials.
What is efficiency?
This law states that energy cannot be created or destroyed, only converted.
What is the Law of Conservation of Energy?
The _____ describes the actions taken by the system to convert inputs into outputs.
Process
Bird flocks, ant colonies, and fish schools are examples of this type of system.
