Mô tả

Two runners illustrate the difference between scalar speed and vector velocity. Runner A completes a circular lap returning to start (displacement = 0). Runner B travels in a straight line (displacement = distance). Direction makes velocity a vector.

Speed vs Velocity

Description

Two runners illustrate the difference between scalar speed and vector velocity. Runner A completes a circular lap returning to start (displacement = 0). Runner B travels in a straight line (displacement = distance). Direction makes velocity a vector.

Phases

# Phase Name Duration Description
1 Setup 2s Two labeled tracks appear
2 Runner A (circular) 4s Runner moves around circular track, returns to start
3 Runner B (linear) 3s Runner moves along straight track with displacement arrow
4 Comparison 3s Side-by-side: displacement vs distance arrows
5 Key Point 2s "Velocity has direction; speed does not"
