if you jumped in the air on a fast moving train would you land in the same spot or move forward with the train

Yes, you will land in the same spot, but please be careful when you try that, don't slip on the floor after jumped in the air on a fast moving train. :-)

pennies will not derail a train. we did it when i was young. the wheels are immense compared to a penny. it is illegal to put things on the track in some states, i imagine, but i'm not sure. the main thing is you must be very careful to not put the penny there anytime when a train is near or expected.you should stay off the tracks and railroad ties between the tracks. by doing so, you do not risk getting your foot caught. i would recommend placing the penny while standing outside the tracks. it is a harmless act ( except for the penny!)....never put rocks or other objects on the track. you might really cause an accident then, or cause someone to be hurt when the train hits the rock.

In the absence of friction, they would fall at exactly the same rate. In the real world, assuming the balls are the same size (which means the lighter ball is less dense) the heavier ball would be faster, because the drag would be similar but the driving force (the weight) would be different.\n\nThe reason they'd travel at the same speed when friction is neglected, is exactly the same reason they free-fall at the same speed; gravitational acceleration is uniform. Placing them on a ramp (or roller coaster track) simply dilutes the effect based on the sine of the angle to horizontal.

run a track backwards...builds butt muscles for leaping

you get off the tracks.

If it's velocity is constant, and you jump straight up, you will land in the same place on the boat, because you, being on it, are travelling at the same velocity, and your horizontal velocity remains constant while you are airborne. (If you think you'll land in the water, then tell me, why is it that when you jump, on an airplane, you don't slam against the back wall?) Of course, you may have a difficult time maintaining your balance when you land, and that may cause you to fall into the water.

If there is no wind speed, no other gravitational pulls present, no magnetic interference, and you throw it perfectly perpendicular up, then it will fall at the same place.\n\nIf you are riding in the passenger seat of a car going 20 mph, and you throw a ball out your window straight out, the ball will have an initial forward speed of 20mph.\n\nThe same concept applies in your question.  Let's say when you look up, the earth is rotating to the left.  When you throw the ball in the air, its initial direction will go a little to the left, but you won't notice it cause you are going a little to the left as well.\n\nHopefully that helps a little bit.  It's a little hard to explain without pictures.

it depends how fast u go. lol

Measured from the ground, its speed is = the car speed + the fly speed measured inside the car.\nThe fly can fly so fast because the air inside the car is steady.\nIts the same if you walk inside a train, your speed measured from the ground will be= the train speed + your speed measured from the train. This doesn't mean you can walk so fast, the train floor is steady.\nIt all depends from the reference point you are measuring. Imagine what the speeds would be if you measure them from outer space, results would be totally different.

theoretically, you would oscillate back and forth until friction slowed you down enough to come to a rest at the center of the earth.  it could be six flags newest attraction!

It simply has less inertia therefore requires less force to move. Since the train applies the same amount of force when it is taking off regardless of its load it will accelerate faster when it is empty instead of full.

If you jump, you will be moving at the same speed as the vehicle just before you left the floor.\n\nWhen in the air, if the vehicle is accelerating, the vehicle will move forward faster than you and consequently, you will land some distance from where you jumped and vice versa.\n\nIf on the other hand, the vehicle was not accelerating, you will land at the exact place you jumped from. Of course, this is not counting air resistance.

This is a cool question.  If you were able to tunnel through the Earth, and fall through, your speed would keep increasing until you reached the graviational center.  At that point, the net gravitational force is zero, because all of the forces cancel.  However, you wouldn't just stop because of your inertia.  You would go right through, but then you would begin to slow down, until you reached the other hole.  Depending on how high you started from the first hole, and lets say you jumped five feet above the hole, you would come to a complete stop five feet above the second hole.  Then you would fall back through and continue that cycle.  (Of course we aren't considering air resistance, which screws everything up! ;0)\n\nGuess how long it would take to make it to the other side of the Earth through that tunnel?  Approximately 42 minutes!  Not a bad way of traveling.\n\nThe other cool thing is, if you were to tunnel from say New York to Berlin, which means the tunnel isn't obviously through the middle of the Earth, it would still take you 42 minutes!

It would depend how fast you peddal and how many stops u make.

Air has a mass.\n\nTrain has a much bigger mass and it's moving.\n\nNewton's law that for every action there is an equal and opposite action means that for as hard as the train is pushing against it, air is pushing back. Air doesn't have a very large mass so a lot more air is needed to stop a train. Pressurized air could stop the train if you could get the train to run headlong into an airlock and jack up the pressure.\n\nAnyway, the air that is unable to push against the engine is pushed out of the way. What you are feeling on the platform is the continuous air current that leads in front of the train as it passes.\n\nThink of a speed boat on the water, the wake of the speed boat is similar to what the air current looks like travelling around the train.

No.  When you departed the aircraft you body would be travelling at the same speed as the aircraft was travelling.    Wind resistance would slow your body down very quickly but you would still land well ahead of the point in which you jumped out of the plane.

You can do this at every single place on earth.\n\nI think you forgot part of the joke.\n\nAn electric train is going down a straightaway at 150 mph due south it goes into a gradual turn slowing to 100mph and is now going East, it goes into another turn at 120mph and is now going North, another turn and it is heading West at 160mph.\nWhich way does the smoke go?
