Lesson 1.1: Distance, Displacement, Speed and Velocity

Welcome! In this lesson, you will explore the fundamental concepts of motion—distance, displacement, speed, and velocity—which are essential for understanding how objects move in our everyday world.

You will learn the difference between distance (how far an object travels) and displacement (the shortest path between two points with direction). You will also discover how speed describes how fast something moves, while velocity goes a step further by including direction.

By the end of this lesson, you should be able to:

  • Clearly define and distinguish between distance and displacement
  • Differentiate speed from velocity
  • Apply formulas to solve simple motion problems
