Relative Velocity of Trains

[bomanton]

the perfect video for relative motion. it would almost seem that the recorder captured it by accident. at least this dope was smart enough to share with us.

Your video was very good. Thanks.

LEASE RITE BACK 2 THIS

rite here we go, me and my friends are arguing about this

if a hover fly was hovering in the middle of a car that was traveling at 90mph

does that mean that the fly is flting with the car at 90mph or is it just hovering at staying within the inside if the car??????

if i dint fly at all tho the fly would crash into the back of the car

soo stressfull pleae sum1 rite backwith a bit of sence please

im 14 so no complicated things

Yes the fly is moving at 90mph if it is not touching anything on the inside of the car.

If it were not, the fly would indeed hit the back of the car. That is why if you are riding in a train moving 90mph, and you jump, you will hit the back of the train.

@RamTerritory

If it were a helium balloon because of inertia and the need to stay at rest both the fly and balloon would not hit the back of the car with the windows closed.

[RamTerritory]

true

@RamTerritory 90mph, and you jump <<

When your body is traveling along with the car at 90 mph it is in an inertial forward frame of travel and should continue with you the car and all the objects in it. Same as throwing a ball straight up and catching it as it falls straight down in the 90 mph car.

[RamTerritory]

Yes.
