Question

[ELI5]How do we move relative to a bus when we jump in one?

In: Physics

Answer 1

In an idealized scenario, you don’t. The bus, the air inside it, and you are all moving at the same speed, with no velocity relative to each other. So, you jump up and come back down in the same spot.

Now, of course, from the frame of reference of someone standing on the side of the road, you’re moving at the same rate as the bus.
