My seems to think that a train is going faster in the front than it is going at the end.... and he even thinks that if you had 10 cars on the express way in a line ,and the front is doing 70 , the next one can only do 69, then next can only do 68 all the way down to car 10 can only do 60 ...would someone tell him all ten can do 70 together...PLEASE

i've heard something like that before too.. good quesion. But I dont think the last car would be going 10 mph slower...but i didnt take physics so I don't know. I think that they all should be travelling at the same exact speed to be able to keep up with each other, if not the last car could get left behind or break away?? I think you are trying to compare it to a car.. like some cars speed up from the front/back but when you step on your brakes it slows down from the front/back. ?? For my car my front brakes wear down faster than by brakes for the back of the car so it slows down in the front

Every part of a train is going the same speed. If there is a variation in the elevation, like on a rollar coaster, the cars are doing a different speed at certain points of the track. like at the top of a hill or through a corkscrew.
If you are driving in a car, the front bumper is doing the same speed as the back bumper.

if a train is all connected together then the whole deal is doing 70........if the back is slower it will pull the train apart and fall behind........same with the line of cars....if everyone is doing exactly the same speed, the distance between won't change.......in your friends example, if the rear car is doing 60 will fall WAY behind the lead car doing 70 real quickly....

I think you got it all wrong. The difference between the front and the back car in a train is resistant. The first car will have more resistance and is less efficient than the car in the back. That doesn't mean that the reamining car is going to be more and more efficient that the car in front. Just a metter of resistance reduction. To much car movies. That is why ducks fly the way they fly. Easy to fly in the back.

There should be a minor speed differential due to the distance from the power source and the resistance from the air, track ect. I am not sure that it would be as much as a mile per hour per car though. If that were true then you would have the power source having to work harder to maintain the rate of travel and there would be a huge problem with trying to compensate for the weight differential from front to back. Cheers

if one carriage on the train is doing seventy then they all have to be going seventy. its called physics
