Scenario: Imagine a car moving at a constant speed on a straight road.
Explanation:
* Velocity: Velocity is a measure of both speed and direction. In our scenario, the car is moving at a constant speed and in a straight line, so it has a constant velocity.
* Acceleration: Acceleration is the rate of change of velocity. If the velocity is constant, then the acceleration is zero.
Graph:
We can visualize this on a velocity-time graph:
* X-axis: Time (t)
* Y-axis: Velocity (v)
The graph will be a horizontal line, meaning the velocity remains constant over time.

Key takeaway: Zero acceleration does not mean the object is stationary. It simply means the object is not changing its velocity. The object can still be moving at a constant speed.
