What are system inputs and outputs? What is a system boundary?. I can describe the components of a system. I can describe a system based on inputs, outputs and boundaries. Two or more parts, working together, to perform a function. Matter and energy flow through systems.

What are system inputs and outputs?What is a system boundary? I can describe the components of a system.I can describe a system based on inputs, outputs and boundaries.
Two or more parts, working together, to perform a function. • Matter and energy flow through systems. Remember the definition of a system…
Energy in some form is an input of a system. Matter can also be an input. Input…
Energy in some form is an output of a system. This is usually the function of the system • Matter can also be an output. Output…
The output is also motion energy.Are there any other energy outputs?
Two or more parts, working together, to perform a function. • Matter and energy flow through systems. • INPUT – An input is something that enters the system. It can be matter or energy. • OUTPUT – An output is something that leaves the system. It can be matter or energy. Adding to our definition…
One output from the person (system) is the energy that is the input of the bicycle system. Sometimes the output from one system can become the input of another system.
Two or more parts, working together, to perform a function. • Matter and energy flow through systems. • Input– An input is something that enters the system. It can be matter or energy. • Output– An output is something that leaves the system. It can be matter or energy. • Subsystem – a subsystem is a system that is part of another system. It’s a system within a system. Adding to our definition…
Boundary – the boundary is the outside border of the system. Depending on where we draw the boundary we can study a system or a subsystem. This boundary includes both the boy and the skateboard in the system. Change the boundary to only study the skateboard system.
Because we look at things systematically to understand them. Sometimes we look at the larger system, and sometimes we look at the smaller system that is actually the subsystem of a larger system. Why?
