When a train enters a station, it creates a suction towards the train
What is the suction effect?
The suction effect is a phenomenon that occurs when a train enters a station. As the train enters the station, it pushes the air in front of it, creating a low-pressure area behind the train.
This low-pressure area causes the air around the train to move towards the train, creating a suction effect.
What causes the suction effect?
The suction effect is caused by the Bernoulli principle, which states that the pressure of a fluid decreases as its velocity increases.
As the train enters the station, it pushes the air in front of it, increasing the velocity of the air. This increased velocity causes the pressure of the air to decrease, creating a low-pressure area behind the train.
What are the effects of the suction effect?
The suction effect can have a number of effects, including:
- It can cause people to be pulled towards the train.
- It can cause objects to be sucked into the train.
- It can cause the train to derail.
How can the suction effect be prevented?
The suction effect can be prevented by a number of methods, including:
- Slowing the train down before it enters the station.
- Installing windbreaks around the station.
- Educating people about the dangers of the suction effect.
