Getting ready for your first physics class? Check out the Physics Skills Mini-Lesson: Proportionality. It is an introduction to an Algebra Skills lesson taught through Finding Physics.
Frequently, in physics, we are interested in seeing how a change in one variable affects another without doing an actual calculation. Expressing the relationship as a proportionality can lead to quick and easy processing of the relationship. For practice differentiating between directly proportional, proportional, inversely proportional, proportional to a power relationship, and proportional to a square root, sign up for the Algebra Skills Workshop (part of the Physics Skills Summer Series) or sign up for a tutoring session focusing on proportionality.
