Physics is a difficult class for many students, as there are many complex terms and formulas that students have to understand and use appropriately. Physics textbooks are also lengthy and heavy, with the formulas and definitions not conveniently located. Because of these constraints, a physics textbook is not useful for studying terms and formulas. A physics terminology study guide is a better resource. A study guide provides students with all of the physics formulas and definitions they need in one place. The definitions are often also simplified, so students can understand the terms in plain English. Many terminology study guides can also be put in a binder, so students can use them as a quick reference when in class or on the go.
