Position Versus Time Graphs
The Position Versus Time graph for a stationary object is a horizontal line.
If an object's Position Versus Time graph is located above the x-axis, the object has a positive position, and if its Position Versus Time graph is located below the x-axis, its position is negative.
The Position Versus Time graph for an object moving at a constant velocity is a straight line. If the Position Versus Time graph has a positive slope, it has a positive velocity, and if it has a negative slope, it has a negative velocity.
In fact, the slope of a Position Versus Time graph is the velocity of the object represented by the graph.
The Position Versus Time graph for an object which is accelerating is a line which is not straight, i.e., a parabola or other curved line.
We will learn more about the Position Versus Time graphs for various types of motion in this week's "Motion Lab Activity."
