Throwing a stone from a moving train involves the same type of calculations as throwing a stone from a stationary platform. The difference is that you now consider the added horizontal velocity imparted by the moving train. If you throw forward, the train's velocity is added to your contribution to the stone. If you throw backward, the train's velocity is subtracted from your contribution to the stone. If you throw sideways, the train's velocity does not alter your contribution to the stone. Whether any of this matters or not depends on friction due to the different air velocities encountered by the stone. Vertical velocity is relatively unchanged by the train's contribution. The stone will still go up (if you include an upward vector in your throw) and it will still go down. The end result is that the stone will hit the ground at some point. That point will be relatively the same in both cases, except for the minor difference due to air velocity.

How does a gear train work?
A number of gears grouped into a single unit is called 'gear train'.If two gear's in mesh eg, a drive gear and a driven gear also constitute a gear train which are called simple gear train and in the simplest form.simple gear train may have more than two gear's.compound,epicyclic,reverted are some other types of gear train's.
When the electric train is moving down a hill the DC motor acts as?
The DC motor acts as a generator. The electricity generated can be used to power the overhead (or third rail) line and used by other trains going up a hill, thus acting as a brake slowing the train going downhill.
Can friction produced by wheels of moving train generate electricity?
yes we can produce electricity by fixing dynamo in traction wheels so heat is produced when the friction of train wheel & track so the dynamo generates an power D.C SUPPLY and is converts into Ac supply so we can use that energy for electric trains use of lights and fans....
Can sensors be used in trains?
It depends what kind of sensor you mean. There are lots of sensors in trains already... for such things as heat/smoke detectors, doors (which stop the train moving unless the doors are closed, fuel, signal sensors..... etc
Imagine you are waiting for a train to pass at a railroad crossing will the train whistle have a higher pitch as the train approaches you or after it has passed you by?
A pleathorea of sounds, just go trackside and listen, from the piercing note of a horn, to the roar of the diesel engine to the click-clack of the wheels on the joints in the rail to the squeal of steel wheel on steel rail, there are hundreds of sounds to enjoy. "Choo Choo" doesn't cut it, sorry. Only the ignorant can agree that any train ever made this sound.
If you are moving to the front of a moving train are you moving faster than the train relative to the earth?
Yes if the train is moving forward, you are moving at the train speed + walking speed relative to the tracks.
Can you have the complete story on why Gandhi was thrown out of a train?
Gandhi was thrown out of a train because a white man needed a first class carriage. Gandhi had brought a first class ticket but as he was black, he was thrown of the train for refusing to move.
Why does a stationary train appear to be moving?
Because there's no such thing as "really" stationary or "really" moving. If the distance between a point on one train and a point on the other train is changing, then a person on either train says that the other train is moving, and both of them are correct. A "stationary" train only appears to be moving if the train you're on is moving relative to that one.
Is there a fluctuation of voltage in a moving train?
Yes, there is a fluctuation of voltage in a moving train
Where was he was thrown off of the train?
he was on a pritorian train,and a station employee said a Indian can't ride on the seat and to go to thehold. But, Gandhi refused.So the sataion employee called the cops so he was thrown of the train.
You are seated in a train that is stopped at a station Use two different reference points to explain that the train can appear to be moving and not moving?
the person standing on the ground, the train is moving and the ground is stationary. but the person on the train looks he is stationary and the ground is moving.
What are Reference points to explain that train is moving?
A person standing on the ground. For the person on the train, ground is moving and the train is stationary.
Why does one train seem to move when other train is already moving?
Relative motion. To talk about a train moving at a certain speed usually means that the train is moving at a certain speed relative to a stationary observer (relative to the ground). This however also means that a passenger traveling in said train would experience the ground (and every other stationary object) as the moving object. This is why a stationary train may seem to be moving to passengers of an already moving train.
What is the motion of the train on a moving track?
A train travels over a FIXED track not a MOVING track.
Who is she climb Everest in one leg?
Arunima Sinha who lost her leg after she was thrown from a moving train two years ago has become the first female amputee to climb Everest on the 21st May 2013.
Would you hear a change in pitch if you are on a moving train and the train whistle blows?
Since you are also on the moving train, the pitch should remain constant.
Why you stay at same place when you jump in moving train or bus?
When you are inside a moving train or bus, you are moving at the same speed as that train or bus, and you have the same momentum, so even when you jump, and are no longer in contact with the floor, your existing momentum will carry you along with the vehicle, under normal circumstances. If you happen to jump at a time with the train or bus is changing the speed or direction of its travel, however, you will find that you do not stay in the same place, with respect to the train or bus. You need to have solid contact with the vehicle for its own changes of motion to alter your own motion.
