Question

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.

Answer 1

I can’t see the graph you’re referring to. Could you upload it or describe the curve between 4 and 6 s?

If it’s a position vs. time graph, use the slope:
- slope > 0 and straight line → moving away from the origin at constant velocity.
- slope = 0 (horizontal line) → not moving.
- slope < 0 and straight line → moving toward the origin at constant velocity.
- slope changing (curve or changing slope) → changing velocity (accelerating).

If it’s a velocity vs. time graph:
- v > 0 and constant → moving away at constant velocity.
- v = 0 → not moving.
- v < 0 and constant → moving toward the origin at constant velocity.
- v changing → changing velocity.

Send the picture or describe the segment and I’ll pick the correct choice.
