Question

Why whenever you drop something out of a car, it falls behind you but when you drop something inside a car, it falls straight down?

In: Physics

Answer 1

There’s no wind resistance inside the car. In other words, the air inside the car is traveling at the same speed and direction as the item being dropped. If the air outside the car was traveling at the same speed and direction as the car, it would appear to fall straight down if dropped outside the car.
