Our premier equation of the week is Newton’s 2nd Law.

This law relates how mass, force, and acceleration interact. It is commonly written like this…

In this equation, the sigma represents a sum, the forces are represented by F, the mass is represented by m, and the acceleration is represented by a. Notice that both sides contain vector symbols. The sum of the forces determine the direction of the acceleration.

This equation is used throughout introductory physics courses, the AP Physics exam, and referred to in nearly every branch of physics.
