Both Cars Moving in Same Direction

Both cars moving forward | Click Start to begin simulation

📐 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)

Velocity of Car A: 10.0 m/s

Car B (Orange Bus)

Velocity of Car B: 6.0 m/s
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
