3 motion motion occurs when an object changes position relative to a certain point whenever an object moves, we compare that object to something in the background that is assumed to be not moving. the background is your frame of reference. Reason: draw a vertical line from the position of 2.5 m to the line of best fit. draw a horizontal line to touch the position axis from the point of intersection of the vertical line and line of best fit. note the position where the horizontal line crosses the position axis. this is the instantaneous position of the athlete at 2.5 s.
Section 2.1 displacement and velocity. describe motion in terms of frame of reference, displacement, time and velocity. calculate the displacement of an object traveling at a known velocity for a specific time interval. construct and interpret graphs of position versus time.

Distance = 10 m displacement = 10 m east distance = 15 m displacement = 5 m east • when distances are in the opposite direction, subtract same direction, add the distances to get displacement distance = 7 m displacement = 5 m ne • when distances are not in the opposite or the same direction, you can’t the distances to get displacement. 1 chapter 2—motion and force section 1—describing motion 2 motion and speed motion—occurs when an object changes its position *motion doesn’t always have to be seen to have taken place reference point used to determine how far something moves –ex: mailbox while driving.
