3. One Dimensional Motion To simplify the concept of motion, we will first consider motion that takes place in one direction.
One example is the motion of a commuter train on a straight track.
To measure motion, you must choose a frame of reference. A frame of reference is a system for specifying the precise location of objects in space and time.
In the train example, any station along the route serve as a frame of reference.
4. Displacement Displacement is a change in position. Displacement is not always equal to the distance traveled. The SI unit of displacement is the meter, m.
