Types of Systems
What is a system?
A group of parts that work together to perform a function.
What does the definition "force" mean?
Any push or pull.
What does "input" mean?
The force, energy or raw materials that you put into a system.
What does the term "side effects" mean?
The unintended or desired outputs of a system.
What does "consumerism" mean?
Linking personal happiness with the purchase of goods and services.
What is a physical system?
A system that needs a group of physical parts to work together to perform a function.
What might an object's results be when force is used?
There is a change in shape and motion.
What does "output" mean?
The task or service that a system performs.
What is a social system?
A system that needs a group people/organisms working together to perform a task and establish relationships.
What is a mechanism?
The part of the system that changes one type of force into another type.
What does "mechanical advantage" mean?
The ratio of output force to input force for a given machine.
What are the similarities between social and physical systems?
Both systems need multiple parts to work together to perform a function/task.
What does the term "newton" mean?
The unit used to measure force.
How do you calculate mechanical advantage?
Input distance divided by output distance.
What does "systems thinking" mean?
Taking into consideration all of the side effects, inputs and outputs of systems.
What is "newton" named after?
English physicist named Sir Isaac Newton.
What does "ideal mechanical advantage" mean?
The mechanical advantage of a machine if all of the input force is converted into output force.
