How Do Things Work on Instagram: "When two objects move at equal speeds but in opposite directions, their motions cancel each other out because they create equal and opposite forces. For example, if one object is moving at 40 km/h to the right and another is moving at 40 km/h to the left, the relative speed between them becomes zero. Mathematically, it’s shown as 40 km/h – 40 km/h = 0 km/h. This means that from a relative motion perspective, both speeds balance perfectly, resulting in no net mov
