**Lesson 2: Position, Distance, and Displacement**
**Objective of this lesson:**
The objective of this lesson is to understand the concepts of position, distance, and displacement, and to differentiate between speed and velocity, including their respective definitions and implications in physical motion.
---
**Define distance:**
Distance is the total length of the path traveled by an object, regardless of the direction. It is a scalar quantity, which means it has only magnitude (how much) and no direction.
---
**Define displacement:**
Displacement is the change in position of an object and is defined as the shortest straight line between the initial and final positions. It is a vector quantity, meaning it has both magnitude and direction.
---
**You run 2 blocks away, turn around and run 2 blocks back home. What is your distance?**
Your total distance traveled would be 2 blocks away + 2 blocks back = **4 blocks**.
---
**What is your displacement?**
Since you end up back at your starting point, your displacement is the shortest distance from your initial position to your final position, which is **0 blocks**.
---
**Define speed:**
Speed is the measure of how fast an object is moving and is defined as the distance traveled per unit of time. It is a scalar quantity.
---
**Define velocity:**
Velocity is the measure of how fast an object is moving in a particular direction and is defined as the displacement per unit of time. Velocity is a vector quantity, meaning it has both magnitude and direction.
---
**What is the major difference between speed and velocity?**
The major difference between speed and velocity is that speed is a scalar quantity with only magnitude (it does not involve direction), while velocity is a vector quantity that includes both magnitude and direction. Thus, two objects can have the same speed but different velocities if they are moving in different directions.
