Our first formal investigation into the world of Newtonian mechanics saw a bowling ball being hurled down 120 feet of hallway.Our investigation of this linear motion (motion in a line) began with timing how long it took the ball to pass by eight marked points, each 15 feet long.
We will use this investigation to determine how to measure and predict the "simple" motion of an object moving in a straight line.
Our first task will be to determine the speed of the ball.
Those students who have taken the time to read this will know that while we can try to figure out the ball's speed every 15 feet mathematically, it will prove far simpler to graph the data and interpret the graph to answer the question of what happened to the ball's speed as it moved down the hallway.

Could we do the same experiment with a train?
To be honest, Mr. Brown, there's no reason why we couldn't. All you need to do is jack up the train and put some low-friction wheels on it. Waitaminute... what's friction?
Just reassemble the Summer program crew thaqt built it and tell them it has to roll.
I hope the Summer Program Crew never needs to re-assemble. The idea was to get them back on track!
