Truck Speed 50 km/h

Drone Airspeed Thrust 0 km/h

External Ambient Wind 0 km/h

Manual Drone Thrusters (Arrow Keys / D-Pad)

Live Vector Telemetry Vector Sum Valid ✓

V_ground (Absolute) 50.0 km/h

V_frame (Observer) 50.0 km/h

V_relative (Observed) 0.0 km/h

Vector Relation:
V_ground = V_frame + V_relative
50.0 = 50.0 + 0.0 km/h

Physics Answer: In Ground Frame, drone moves at 50 km/h. In Vehicle Frame, drone is stationary at 0 km/h. Both are physically correct.
