What's the difference between independent and dependent variables?

May 5th, 2015

Independent variables are values that can be changed in a given equation or experiment. Think of an independent variable as your input. An independent variable represents information that you put in to the equation.

Dependent variables are values that result directly from the independent variable. Ultimately, they depend on the independent variable.
 Consider this example..

F = ma
 
When measuring the acceleration of an object, the mass does not change. Therefore, it remains constant. The independent variable in this formula would be force. Force can be changed, and a greater force results in a greater acceleration.

In F=ma, what are the independent/dependent variables then?

F is the independed variable while a is the depended variable.
