* Displacement: Displacement is the change in position of an object.
* Constant Velocity: Constant velocity means the object is moving at a steady speed in a single direction.
* Slope: The slope of a displacement vs. time graph represents the velocity.
Visualization:
Imagine a car driving down a straight road at a constant 60 mph.
* Time (x-axis): As time passes, the car continues to move.
* Displacement (y-axis): The car's distance from its starting point increases steadily.
Since the car's velocity is constant, the distance covered in each equal time interval will be the same. This creates a straight line on the graph. The positive slope indicates that the displacement is increasing as time increases, meaning the object is moving in a positive direction.
Key Points:
* The steeper the slope, the faster the object is moving.
* If the velocity were negative, the line would have a negative slope (sloping downwards).
* A horizontal line on the displacement vs. time graph represents an object at rest (zero velocity).
