Do not stand too close to moving?
“ When a train moves, there is a matter wave attached to it. Waves move from positive to negative. Outside of train is positive and inside is negative. So, the train may pull us towards it if we stand very close to it.”
Why do we get pulled towards the train when the train moves very fast?
According to Bernoulli’s theorem, greater is the velocity, smaller is the pressure and vice-versa. Therefore, the air pressure behind the person becomes bigger than the air pressure between the person and the train. Due to this pressure differences, the force acts on the person towards the train.
What happens if you throw a ball in a train?
When a person throws a ball up in a moving vehicle, say, a train, the ball does come straight back to thrower as though the train were at rest. So if the train moves with a constant velocity, the ball will exactly return to the thrower.
Why low pressure area is created near the train?
When a truck moves very fast, it created a low pressure area, so dusts are being pulled along in the low pressure area. If we stand very close to railway track in the platform, when a fast train passes us, we get pulled towards the track because of the low pressure area generated by the sheer speed of the train.
How is Bernoulli’s principle used today?
Bernoulli’s principle can be applied to many everyday situations. For example, this principle explains why airplane wings are curved along the top and why ships have to steer away from each other as they pass. The pressure above the wing is lower than below it, providing lift from underneath the wing.
What is Bernoulli’s principle in planes?
Bernoulli’s Principle states that faster moving air has low air pressure and slower moving air has high air pressure. Air pressure is the amount of pressure, or “push”, air particles exert. It is this principle that helps us understand how airplanes produce lift (or the ability to get into the air).
What would happen if humans could fly?
Shipping would still be needed, so roads, highways, trains, ships and even planes would still be needed to move lots of things efficiently. Garbage pick up would still be needed so even sidewalks and small roads among houses would still be needed. People can fly anywhere and ignore roads just fly over buildings.
What if humans had tails?
Tails would play a role in how humans maintained balance, depending on how long they were. Sports and hand-to-hand combat would be dramatically different. Tails would be sexualized. Tail length and girth would become a major factor in how males were perceived and “tail envy” would be ubiquitous.
What if humans had no emotions?
Without emotions, our lives as humans would be void and pointless, with no motivation or in spiration to do great things. We would live in a dull world where nothing had meaning. Ambition would be not captured or understood and we would operate like robots or artificial intelligence.
What if humans had an exoskeleton?
If a large animal such as a human being had a thin light exoskeleton, there would be several problems. Since the exoskeleton would not be able to hold its shape, it would be difficult to keep the vital organs protected and the organism would be subject to damaging levels of stress just by moving around.
