Understanding Velocity-Time Graphs for Uniform Velocity
Uniform velocity means that an object's speed and direction remain constant. The velocity does not change over time.
Interpreting the Velocity-Time Graph
In a velocity-time graph:
- The vertical axis (Y-axis) represents velocity.
- The horizontal axis (X-axis) represents time.
For an object moving with uniform velocity, its velocity value stays the same at all points in time. On the graph, this is shown as a constant value on the vertical axis. A constant value over time is represented by a horizontal line.
Therefore, a straight line parallel to the time axis indicates that the velocity is constant, which is the definition of uniform velocity.
Matching Graph to Options
- A curved line or a sloping line indicates a changing velocity (acceleration or deceleration).
- A straight line parallel to the time axis indicates a constant velocity (uniform velocity).
This corresponds to Option 3.
