Please provide a rating, it takes seconds and helps us to keep this resource free for all to use

There are 4 lessons in this physics tutorial covering Speed and Velocity in 1 Dimension. The tutorial starts with an introduction to Speed and Velocity in 1 Dimension and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Speed and Velocity in 1 Dimension. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

• The meaning of Speed
• How to calculate the speed of a moving object?
• The difference between average and instantaneous speed
• The meaning of velocity and how does it differs from speed
• How to calculate the velocity of a moving object?
• The difference between average and instantaneous velocity
• Expressing the velocity as the gradient (slope) of the Position vs Time graph

## Introduction

In the previous two tutorials "Displacement and Distance in One Dimension" and "Displacement and Distance in Two and Three Dimensions", we discussed extensively about these terms as concepts related to the motion of objects.

Do you think it is enough to know the Displacement and Distance of an object to have an idea on how the object is moving? Why?

Many people use the terms "Speed" and "Velocity" without making any distinction between them. They consider these terms as synonyms. But are they really so?

In this tutorial, we explain the meaning of these concepts using a very basic terminology, so the readers will understand easier the abovementioned concepts and the difference between them.
