Curiosity and boredom (at work):
The problem can also be compared to someone who can (so to speak) jump high in a moving bus. Suppose the person jumps, will he come back down in the same place? Or ‘more to the back’ than in a stationary bus?
Answer
The fly goes back. The jumping person moves backwards. Newton already knew: inertia or inertia. A body that has no force acting on it will maintain its speed (or lack thereof). If you make a left turn with your car, your body wants to go straight ahead (it seems as if you are being pushed to the right in your car).
