Train Lab Train Lab Problem- What's the acceleration of the L train' Materials- Measure meter, stop watches, L train Procedure- First, the person in charge examines the platform briefly. Then he takes 11 people and places that at approximate. equal distances from each other over the entire platform. These are not going to be exactly accurate, as they are just a quickly formed hypothesis of the “equal” distance people people. Once the people are in their positions, they are handed a stopwatch by the safety people and are to remain in these spots until told to do otherwise. The person closest to the “beginning” of the platform (the first place the train passes coming into the station) is given the measure meter. Next, as the train enters the station, all stoppers get ready. As soon as the train starts to move out of the station, all stoppers start their watches and stop their watches when the back of the train passes them. Then, the person with the measure meter measures the distance between each person to get the displacement. With the time and displacement, one can get velocity. Then, we calculate the changes in velocity to train, people, lab, velocity, station, numbers, accurate, total, person, intervals, displacement, didn’t, watches, time, thus, strange, stoppers, possible, platform, passes, meter, measure, make, m/s, equal, each, distance, certain, between, accelerations, acceleration, yet, very
