In a lab focusing on net force versus acceleration, the discussion centers on identifying the dependent and independent variables. Net force is considered the independent variable, as it is controlled by the experimenter, while acceleration is the dependent variable, as it changes in response to the net force applied. The equation F=ma illustrates this relationship, where acceleration can also be expressed as a = F/m. The key takeaway is that the independent variable is what you manipulate, and the dependent variable is what you measure. Understanding these roles is crucial for accurately interpreting experimental results.
