The property that makes it hard to stop a moving train is its momentum. Momentum is a vector quantity that depends on both the train's mass and velocity. The higher the train's mass and speed, the greater its momentum and the more force is needed to stop it.
The motion of a train on a moving track depends on the reference frame you choose. In the train's frame of reference, it may appear stationary or moving at a constant speed. However, in an external, stationary frame of reference, the train would appear to be moving at a different velocity that combines the train's speed with the speed of the track.
The passengers reference point ! The passengers are moving at the same speed as the train.
The type of friction involved in a train moving along a track is mainly rolling friction. This occurs between the wheels of the train and the tracks they roll on. Rolling friction is less than sliding friction, allowing the train to move more efficiently.
Yes, it is possible for the train to appear to move while it is at rest if another train next to it starts moving, creating an illusion of motion. Additionally, if there are vibrations or movements in the surroundings that are transferred to the stationary train, it may also feel like it is moving.
Yes. For example, if you are sitting on a train that is at rest, but there is a train on the next track that is moving, it may appear that you are moving.

People sometimes put their ear on a railroad track to see if a train is coming. It does not work because of the iron rail, it works because of the vibrations the train makes on the rail as it is moving.

Did who fall on the train track?
A train track is stationary
Because there's no friction between the train and the track. In an 'ordinary' train, friction between the wheels and the rails takes a lot of energy to overcome before the train starts moving. In a Maglev train, the train itself actually 'floats' above the track on a 'cushion' of magnetic foirce. With no friction to slow it down, the train is capable of much higher speeds.
Yes. For example, if you are sitting on a train that is at rest, but there is a train on the next track that is moving, it may appear that you are moving.
Suppose that 1st car is X-car and the 2nd car is Y-car. Answer: After the collision, car X is no linger moving, but car Y is moving.
Yes if the train is moving forward, you are moving at the train speed + walking speed relative to the tracks.
A train wreck or train crash is a type of disaster involving one or more trains. Train wrecks often occur as a result of miscommunication, as when a moving train meets another train on the same track; or an accident, such as when a train wheel jumps off a track in a derailment; or when a boiler explosion occurs. Train wrecks have often been widely covered in popular media and in folklore.Because of the potential for multiple deaths and extensive property damage and economic loss, the law treats the intentional wrecking of a train as extremely serious, some jurisdictions providing for life imprisonment even where the wreck does not result in death, and the death penalty where it does.
