Distance and Displacement


Distance and displacement are two quantities that may seem to mean the same thing yet have distinctly different definitions and meanings.
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

To test your understanding of this distinction, consider the motion depicted in the diagram below. A physics teacherwalks 4 meters East, 2 meters South, 4 meters West, and finally 2 meters North.

Scalars and Vectors

Scalars and Vectors

Physics is a mathematical science. The underlying concepts and principles have a mathematical basis.
Throughout the course of our study of physics, we will encounter a variety of concepts that have a mathematical basis associated with them. While our emphasis will often be upon the conceptual nature of physics, we will give considerable and persistent attention to its mathematical aspect.

The motion of objects can be described by words. Even a person without a background in physics has a collection of words that can be used to describe moving objects. Words and phrases such as going fast, stopped, slowing

Describing Motion

Introduction to the Language of Kinematics

A typical physics course concerns itself with a variety of broad topics. One such topic is mechanics -


the study of the motion of objects. The first six units of The Physics Classroom tutorial will involve an investigation into the physics of motion. As we focus on the language, principles, and laws that describe and explain the motion of objects, your efforts should center on internalizing the meaning of the information. Avoid memorizing the information; and avoid abstracting the information from the physical world that it describes and explains. Rather, contemplate the
