Question

Why is everything going behind when we travel in a bus or a train

Answer 1

Because there is no relative velocity between the object and us.

Explanation:

• When we are traveling in a bus or train we are moving with the velocity of the bus or train.
• Tress, buildings, and other things stay and don't move around when we are traveling.
• In fact, we are moving with the velocity of the vehicle.
• The only reason why we see them moving behind is that there is no relative velocity between us and things.
