Interpreting Position vs. Time Graphs Mr. Rana 9/20/12

Bell Ringer (on loose leaf paper with name, date, period) Graph the following points: (0,0) (0,1) (1,1) (1,2) (1,3) and (2,3) Now connect them with a line. You must be in your assigned seat to be marked present.

Displacement Δx = displacement x f = final position x i = initial position

Position vs. Time Graphs

Construct a position vs. time graph for the following data:

At t = 0, you are at position _______. At t = 2, you are at position _______. At t = 3 you are at position _______.

How can we get a horizontal line? If we don’t move at all, the position vs. time graph will be a horizontal line.

How can we get a line with positive slope? If we leave the origin and keep moving, we get a positive slope (upward).

How can we get a line with negative slope? If we go toward the origin and keep moving, we get a negative slope (downward).
