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:

In a position - time graph, the slope of the graph represents velocity. Between 4 and 6 seconds, the position of the object does not change. A zero slope in a position - time graph means velocity \(v=\frac{\Delta x}{\Delta t}=0\) (where \(\Delta x\) is the change in position and \(\Delta t\) is the change in time).

Answer:

The object is not moving.
