# position time graph negative velocity

1. IF THERE IS SLOPE/diagonal line ON A VELOCITY vs. TIME graph it means it is accelerating, if it is at a straight horizontal line it is moving at a constant speed. 5) The change in position of an object (displacement) can be calculated from a velocity versus time graph by calculating the area between the velocity graph and the horizontal axis. Area above the "v0" axis is positive, area below the "v0" axis is negative. 4/13/2015 Position-Time Graphs 3 Constant Velocity Motion described as a constant, positive velocity results in a line of constant and4/13/2015 Position-Time Graphs 14 3 Trials 4/13/2015 Position-Time Graphs 15 Interpretation of p-t Graphs Recall: On a p-t graph a negative slope In order to find the velocity of an object in a position vs. time graph, you might want to understand and see how a position vs. time graph looks like first.The 3rd graph tells you that the object is moving at a negative constant speed because the line is straight but this time is going down. Now for a velocity-time graph (and I agree, they are more challenging to interpret!). Any point above the time (horizontal) axis is positive velocity, meaning the object is moving forward .Negative velocity must mean movement in the opposite direction. to examine and compare the shapes of position-time and velocity-time graphs for objects moving in one dimension. ProcedureSketch of Velocity-Time Graph. 0 Positive. 0. 0 Negative. 0. 0 0 Positive . Note that a motion described as a constant, positive velocity results in a line of constant and positive slope when plotted as a position-time graph.The graph on the right has similar features - there is a constant, negative velocity (as denoted by the constant, negative slope). positive direction, then back in negative direction b) (in blue) object moves away from origin in negative direction. 10s.

3. a) Draw the velocity vs. time graph for an object whose motion produced the position vs time graph shown below at left. To find the distance traveled from a velocity versus time graph, we use a graphical interpretation of the equation d vt.Test your knowledge.
