Introduction to Physics: Displacement and Velocity

Distance is a scalar quantity measuring the total path traveled. For example, the distance between two cities might be $100\text{ miles}$ . Distance is always positive.
Displacement is a vector quantity that accounts for both magnitude and direction. It is the difference between the final position and the initial position ( $final - initial$ ).
Directional conventions define movement towards the East or North as positive displacement, and movement towards the West or South as negative displacement.
Example: If John walks $8\text{ meters East}$ ( $+8$ ) and then $3\text{ meters West}$ ( $-3$ ), his total distance is $11\text{ meters}$ , but his net displacement is $+5\text{ meters}$ .

Speed is associated with distance; it is a scalar description (e.g., $200\text{ miles}$ ).
Velocity is associated with displacement; it is a vector description (e.g., $300\text{ miles North}$ ).
The formula for average velocity is: $\bar{v} = \frac{d}{t}$ , where $d$ represents displacement and $t$ represents total time.

Response: The sparkles, the baby eyes, and the cat.
Participant Question/Prompt: What does the castle mean?
Response: The castle emoji is used as a substitute because "many people" is difficult to spell.
