sounds stupid but i want to settle a disagreement =
When you jump on a moving bus, do you land further back than where you left off because when you are in the air, the bus isnt moving you. so surely you should technically land in a different spot as the bus is moving underneath you.
I hope you understand what i mean.

No, you would land in the same part of the floor of the bus from where you jumped. The reason is that you have momentum from the bus. You are moving at the same speed to begin with, so you are still moving that fast when you land.
However, if you jumped while the bus was accelerating, decelerating, or turning, then you would land in a different spot. The bus floor has to be touching your feet to get you to accelerate along with it.

You are going the same speed as the bus when you jumped, and in the amount of time you were in the air, there wasn't enough time for you to slow down enough to end up further back on the bus. Now if you were in the back of a pickup truck, and jumped, then the wind blowing against you would blow you backward. But inside a bus, there's no wind to blow against you when you jump, so you land in the same spot.

Not stupid; it takes some thinking.
If you are on the bus and it's moving at a constant speed, then you can think of yourself as two completely separate objects, B (bus) and Y (you). B and Y both have inertia - a body at rest tends to stay at rest, a body in motion tends to stay in motion.
If B and Y are moving at the same speed, and Y moves VERTICALLY but does not change its HORIZONTAL speed, then B and Y will still be moving at the same speed.
This is what happens when you jump. You (and Y) maintain a constant speed even though you aren't touching the bus because you have inertia.
Because B and Y are moving at the same speed, then if Y were to come back down, but maintain its own constant horizontal velocity, then it will be exactly even with B again.
This is what happens when you come back down from jumping.
Now, if after Y were to jump, B were to accelerate (or decelerate), but Y were to maintain its own constant velocity because it has intertia (a body at rest tends to stay at rest, a body in motion tends to stay in motion), then B would no longer be even with Y.

You land on the same spot becuase you are moving with the bus. That's the reason why your body keeps moving forward when the car brakes because you where going the same speed as the bus

You do land farther back on the buss but due to relativity your jump only lasts for at most 1 second that isn't a very noticeable difference in your landing position but consider your position in relation to the speed of the bus for example the bus is going 45 mph you jump your position spatially in relation to the landscape outside is substantially different when you land.

Not unless the bus changes speed while your in midair. Otherwise, you and the bus are going the same speed the whole time your in the air
