Title: Understanding Velocity Graphs for Objects on a Frictionless Ramp

---

**Question:**
Which of the following could be a velocity graph for an object accelerating down a frictionless ramp?

**Image Explanation:**
The image shows a segment of a quiz or educational material displayed on a laptop screen. The question is about identifying the correct velocity graph for an object accelerating down a frictionless ramp.

**Graph Description:**

1. **Graph 1:**
    - **Axes:** 
        - x-axis represents time.
        - y-axis represents velocity.
    - **Data Representation:**
        - The graph shows a horizontal line.
        - The horizontal line is at a velocity of -2 units.
        - It extends from the left end of the graph (time = 0) to the right end (time = 10).
    - **Interpretation:**
        - This graph indicates constant velocity, with no change in speed over time.
        - This is not representative of an accelerating object, which would show a change in velocity.

Note: An accurate graph for an object accelerating down a frictionless ramp would show an increase in velocity over time, resulting in a sloping line on the graph.

This description aims to help students identify and understand the correct characteristics of a velocity graph for an object accelerating down a frictionless ramp. Typically, this graph would show a straight, diagonal line sloping upwards from left to right, indicating a continuous increase in velocity.
