- In a velocity-time graph:
- The Y-axis represents Velocity.
- The X-axis represents Time.
- Thus, the variable plotted on the Y-axis is Velocity.

Understanding Velocity-Time Graphs
In a velocity-time graph, the primary focus is on understanding how an object's velocity changes over time. Here’s a detailed breakdown of why velocity is plotted on the Y-axis:
Key Variables on the Graph
- Y-axis: Represents the variable that is being measured or observed, which in this case is velocity.
- X-axis: Represents time, which is the independent variable.
Definition of Terms
- Velocity: A vector quantity that indicates the speed of an object in a specific direction.
- Speed: A scalar quantity that refers only to how fast an object is moving, without direction.
- Time: The ongoing sequence of events that occur, representing the duration of motion.
- Distance: Total path covered by an object, irrespective of direction.
Why Velocity on Y-axis?
- Measurement Focus: The Y-axis is used for the dependent variable. In this scenario, velocity changes as time progresses, making it the dependent variable.
- Graphical Representation: By placing velocity on the Y-axis, we can easily visualize how the speed and direction of an object change over a given time interval.
Conclusion
In summary, in a velocity-time graph, velocity is plotted on the Y-axis because it is the dependent variable that depends on the time elapsed. This graphical representation allows for a clear understanding of motion dynamics, making it essential for analyzing and interpreting an object's movement.
