How is this different from a distance-time graph?
Answer:
its devavtion is different from the distance changes process
Explanation:
A speed-time graph and a distance-time graph represent different aspects of motion. A horizontal line on the former indicates a constant speed (zero acceleration), while a straight, upward-diagonal line on the latter shows constant speed. A flat horizontal line on a distance-time graph shows no movement.
A speed-time graph and a distance-time graph each depict different aspects of motion. A horizontal line on a speed-time graph does indeed indicate constant speed or zero acceleration; the object is moving at a constant speed. However, a distance-time graph shows how the position of the object changes over time.
Let's take an example. If a car is traveling at a constant speed, on a speed-time graph, this would be represented by a horizontal line. The height of the line above the time axis represents the constant speed.
On a distance-time graph, a car moving at constant speed will be represented by a straight line with a positive slope. This is because the position of the car is continuously changing (it's covering distance), and at a constant rate. The slope of the distance-time graph gives us the speed of the car.
So, while a flat horizontal line in a speed-time graph indicates constant speed, a flat horizontal line in a distance-time graph would indicate no change in position, i.e., the object is not moving at all.
