📐 Formula: Relative Velocity VAB = VA - VB
🚗 Both cars moving forward: When objects move in the same direction, relative velocity is the difference of their speeds.
VAB (Car A relative to Car B)
0.0 m/s
Car A's speed relative to Car B
VBA (Car B relative to Car A)
0.0 m/s
Car B's speed relative to Car A
Simulation Controls
Car A (Green Bus)
Car B (Orange Bus)
VAB = VA - VB
Relative Velocity = Speed of A - Speed of B
When both move forward, relative velocity = difference of speeds
Example Scenarios
Textbook Example
Car A: 10 m/s | Car B: 6 m/s
Equal Speeds
Both at 8 m/s → Relative velocity = 0
Faster vs Slower
Car A: 15 m/s | Car B: 5 m/s
One Stationary
Car A: 12 m/s | Car B: Stationary
