I go to work on the train and I get on at the back and get off at the front. I can choose when to walk through the train. If I walk when the train is accelerating forwards it is harder for me to get to the front and I do more work. If I make the trip when the train is stopped or at a constant speed I do less work. I travel the same distance both times, from one station to the other and the length of the train.
Depending on when I make the trip the amount of work I do varies but I have the same amount of energy (none) at the end of the trip
How does the conservation of energy apply here?
Thanks
