Why we should not stand near a fast moving train?
When fast moving train passes on a rail, then the velocity of air stream in between the rail and the person standing near rail will be very large as compared to the velocity of air streams on the other side of person away form the rail. …
Why does atmospheric pressure push you toward a moving train?
If the air between you and the train is moving quickly in the same direction as the train and the air on the other side of you is stationary (or at least not moving so fast) then the pressure of the air near the train will be lower than the pressure on the other side of you and there will be a net force pushing you …
Why is it dangerous to stand near the edge of the platform when fast train is crossing it?
Answer: When a train enters a platform, a region of low pressure is created around the train and if a person stands on the edge, he might gets pulled towards the train, so it is dangerous to stand near the edge.
Why the train in which we are sitting appears to move while it is at rest give reason?
Yes it is possible because the train may be motion (moving) for the person who is outside the train but for passengers inside the train may be at rest (idle) as motion and rest are relative terms. While sitting in the train you will feel that the train in which you are sitting is moving in a forward direction.
Are the passenger of moving train at rest or in motion with respect to a man sitting in the station?
Passengers sitting in a train are at rest with respect to each other.
Why did I get pulled into a moving train?
The air right next to the train is traveling at approximately the same speed as the train (no-slip boundary condition). As the air velocity goes up, the local static pressure goes down (conservation of energy). The lower static pressure near the train was likely pulling you in.
Why doesn’t a train attract you when it passes by?
It is Bernoulli’s principle. When the speed of fluid increases, internal pressure in the fluid decreases. When the train is moving fast, the pressure around it drops. And the high pressure region pushes things in it’s vicinity towards reduced pressure region. So the train didn’t attract you but high pressure region pushed you towards train.
When a fast moving train cross a person standing near track?
When a fast moving train cross a person standing near a railway track, the person has a tendency to fall towards the train. This is because Solution. According to Bernoulli’s theorem, greater is the velocity, smaller is the pressure and vice-versa.
How can you tell if a train is moving towards you?
Sounds from objects moving towards you sound higher pitched than when stationary and sound lower pitched when moving away. If you know what the train horn sounds like standing still, you can figure out if a train in moving towards or away from you and how fast just by measuring the frequency (pitch) of the sound you hear!
