How do you use a graph to show someone's motion?
By using the distance, speed, and acceleration, to show on the graph the constant speed of each car
Does a horizontal line on a speed time graph show constant speed?
yes
If a graph shows distance on the vertical axis and time on the horizontal axis and the speed is steadily increasing Will it be a straight diagonal line?
No, if the speed is steadily increasing, the graph will not show a straight diagonal line. Instead, it will show a curve that is sloping upwards, indicating acceleration. This is because as time progresses, the speed is increasing at a constant rate, resulting in a curved line on the graph. A straight diagonal line would indicate a constant speed over time.
Does a horizontal line on a distance time graph show constant speed?
No. It shows zero speed. Velocity is distance/unit time. The slope of the line shows change in distance / change in time. Since distance never changes as time changes, the change in distance is zero. Alternatively, the slope of a horizontal line is zero. If zero speed is considered "constant", then yes, it does show constant speed but the speed is zero.
What does the line on a speed or time graph show?
The shape and slope of the line on a graph illustrates the qualitative and quantitative relationship between the variables plotted on the axes of the graph. Sadly, there is no such graph as a "speed or time" one.
