The Science of Physics Mathematics

What We Want to Know… How do tables and graphs help understand data? How can we use graphs to understand the relationship between variables?

Graphs and Tables Graphs and tables help us see patterns and use it to make estimations for when there is no data. Time (years) Height (cm) h (cm) t (years)

Variable Relationships Mathematics help analyze and summarize observations by describing relationships between different variables. time speed distance = Most physical phenomenon described by physics follow 1 of 5 basic relationships between the variables.

Variable Relationships No relationship between variables Direct relationship y is directly proportional to x y x y x

Inverse y is inversely proportional to x Square y is proportional to the square of x Square root y is proportional to the square root of x y x y x y x

What We Know… How do tables and graphs help understand data? How can we use graphs to understand the relationship between variables?
