which graph shows an object moving away from the origin and then back towards it?

Explanation:

Step1: Analyze object moving away

When an object moves away from the origin, the distance - time graph should show an increase in distance over time.

Step2: Analyze object moving back

When the object moves back towards the origin, the distance - time graph should show a decrease in distance over time.

Step3: Check each graph

In the first graph, distance increases and then levels off. In the second graph, distance only decreases. In the third graph, distance only increases. In the fourth graph, distance first increases (moving away) and then decreases (moving back).

Answer:

The fourth graph (the one with a triangular - shaped graph where distance first goes up and then comes down) shows an object moving away from the origin and then back towards it.
