Question

which description best matches the motion shown in the graph? this graph shows an object moving forward and then backward. this graph shows an object moving at a constant velocity. this graph shows an object slowing down and then speeding up. this graph shows an object speeding up and then slowing down.

Explanation:

Step1: Analyze the first part of the graph

The slope of the position - time graph is positive and increasing in the first part. A positive slope in a position - time graph means the object is moving forward, and an increasing slope means the velocity is increasing (speeding up).

Step2: Analyze the second part of the graph

The slope of the position - time graph is positive but decreasing in the second part. A positive slope still means the object is moving forward, and a decreasing slope means the velocity is decreasing (slowing down).

Answer:

This graph shows an object speeding up and then slowing down.
