In Physics class, freshmen are studying how forces impact the acceleration of an object and/or a system of objects by working with carts and pulleys.
The goal of the experiment is for them to collect data through which they discover Newton's Second Law, that the net force applied to a system divided by its mass is equal to the acceleration of the system. Not knowing what to expect, the lab allows them to discover this law. This whole idea of discovering each equation each unit through experimentation is at the foundation of Latin's physics curriculum. All important ideas and concepts and equations should have empirical support (and derived empirically).
