Imagine you’re sitting on a train that’s moving. You look out the window, and it feels like the trees outside are going backward. But actually, your train is moving forward! It’s like watching a movie: when you move past things, they seem to be moving in the opposite direction. This happens because of perspective, how our eyes see things that are far away or close by. If you're sitting still and the train next to yours starts moving, it might look like you are moving instead.
Examples
- When you're on a moving train, it looks like trees outside are going backward even though your body feels like it's moving forward.
- You sit still on a train that starts moving, suddenly, the train next to yours seems like it’s moving instead of yours.
- A car moves past you while you're driving, you feel like you’re moving forward, but the car outside looks like it’s going backward.
