Title: 1_5 Formulae and Transposition
Course: HELM Workbooks 2023-2024 > Section: HELM 1: Basic Algebra

Formulae are used frequently in almost all aspects of engineering in order to relate a physical quantity to one or more others. Many well-known physical laws are described using formulae. For example, you may have already seen Ohm’s law, \(v = iR\), or Newton’s second law of motion, \(F = ma\). In this Quiz we describe the process of evaluating a formula, explain what is meant by the subject of a formula, and show how a formula is rearranged or transposed. These are basic skills required in all aspects of engineering.
