Naming the quantities in a model
Define measurable quantities and their roles before constructing a model
Problem types
- Define the quantities in a model
Builds on
- Choosing units and a sensible precision
- Dependent and independent variables · Earlier idea
Naming the independent and dependent variable begins modeling, and each modeled quantity also needs a unit.
Leads to
- Linear equations from constraints · See it applied
A linear equation for a situation needs defined quantities first: a variable with units for each changing quantity, and a rate in dependent unit per independent unit.
- Systems that model two constraints · See it applied
A system of equations for a situation needs each quantity defined first, with a variable and a unit for each.
- Modeling with geometry · See it applied
A geometric model of a situation needs defined quantities such as length, area and their units.
