Question

interpreting a position vs. time graph
position vs time
using the graph, describe what is happening between 4 and 6 seconds.
the object is moving away from the origin at a constant velocity.
the object is not moving.
the object is moving toward the origin at a constant velocity.
the object is changing velocity.

Explanation:

To interpret the position - time graph between 4 and 6 seconds, we use the concept that in a position - time graph, the slope of the graph represents velocity. A horizontal line (slope = 0) means the object's position is not changing with time, so the object is at rest (not moving). Between 4 and 6 seconds, the graph is a horizontal line, which implies that the position of the object does not change as time progresses. So the object is not moving.

Answer:

The object is not moving.
