A fast-moving train. apex community (;
If you see a clock on a very fast train moving by you, you would observe that the clock appears to be moving faster than normal due to the train's speed. This is because of the relative motion between you and the train.
Probably for the same reason you don't want to hang out next to a sinking ship or stand under a passing airplane - the air or water nearby is being pushed aside and creating a vortex. The air disturbance along with the ground vibrations may cause you to lose your balance and possibly fall into the passing train and maybe die. When a train is moving at a high speed; the velocity of air increases; according to bernoulli' s theorem, as the velocity increases, the pressure decreases. Thus the place where we are standing is a region of high pressure and the place where the train is moving is a region of low pressure. We are pulled from a region of high to a region of low pressure.
The sensation of being sucked towards a fast-moving train is due to the change in air pressure created as the train passes by. The speed of the train causes a sudden decrease in air pressure around the person, leading to a perceived force pulling them towards the train.
When the aircraft levels out horizontally, or if its a sea vessel again when the walking surface is horizontal.. Walking in a moving tractor trailer would be dangerous if theres no force holding the person when the vehicle breaks fast. What is OK?
Yes. Train tracks are metal because if they were wooden such fast moving train wheels will cause friction on the wooden tracks, setting them on fire.
This cannot be answered properly without knowing how fast you are moving.
No, a fast-moving train cannot suck people off the platform by forming an area of low pressure. Trains displace air as they move, but they do not create a vacuum or low-pressure zone strong enough to pull people towards them. The force of air resistance and the distance between the platform and the train are too large for this to occur.
It is dangerous to jump from a fast moving train because you can get killed. You can also get hurt as well. You may jump off the train and land the wrong way and break something or become severely injured.
Any movement must be specified - and measured - in relation to something. If you are inside a closed train, you see the walls of the train, and can measure or estimate your movement compared to the train, or the train's movement compared to your own position. But - assuming you don't see the outside - you don't know how fast the Earth is moving backwards with respect to the train (or the train with respect to Earth).
The fast train from Lisbon to Oporto is the Alpha Train.
You are moving at 3 mph relative to the ground since you are walking at 2 mph towards the rear of the train while the train is moving at 5 mph towards the North. This is calculated by subtracting your walking speed from the train's speed.
