Mention one use of velocity-time curve of an accelerating object.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Velocity-Time Curve**: The velocity-time curve is a graphical representation that shows how the velocity of an object changes over time. The x-axis represents time, while the y-axis represents velocity.

2. **Identifying the Relationship**: The slope of the velocity-time curve is crucial as it represents the acceleration of the object. Mathematically, acceleration (a) is defined as the rate of change of velocity with respect to time, which can be expressed as:
\[ a = \frac{dv}{dt} \]
