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

There are 3 lessons in this physics tutorial covering Speed and Velocity in 2 and 3 Dimensions. The tutorial starts with an introduction to Speed and Velocity in 2 and 3 Dimensions 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 2 and 3 Dimensions. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

• The steps to calculate the average speed in two and three dimensions?
• How can we calculate the instantaneous speed in two and three dimensions?
• The same for the average and instantaneous velocity in two and three dimensions

## Introduction

In the previous tutorial "Speed and Velocity in One Dimension," we explained the basics of these two concepts outlining at the same time the differences between them. Now, we will deal with Speed and Velocity in two and three dimensions. Obviously, the physical principles in both cases are the same; only the mathematical apparatus used to find the values is more complicated (just like when dealing with Displacement and Distance in two and three dimensions compared to the calculation of the same quantities in one dimension).

Therefore, in this tutorial we will use more a Mathematical-based approach than a Physical one because the physical principles of the quantities involved have already been explained in the previous tutorials of this section.
