Can a graph ever have a straight vertical line on a speed graph?
In a speed graph, a straight vertical line represents an infinite speed, which is not physically possible. Such a line would imply that an object is covering a distance instantaneously over a finite time interval, violating the principles of physics. Therefore, a speed graph cannot have a straight vertical line.
With regard to question16 above could any part of the speed line ever become perfectly vertical why or why not?
Oh honey, let me break it down for you. In a speed-time graph, the speed line can never be perfectly vertical because that would mean the speed is changing instantaneously, which is not physically possible. Speed is the rate of change of distance with respect to time, so a vertical line would imply an infinite speed, and last time I checked, we're not living in a Fast and Furious movie.
A graph shows distance on the vertical axis and time on the horizontal axisif the speed is steadily increasing what will the line representing speed look like on the graph?
If a graph shows distance on the vertical axis and time on the horizontal axis, and the speed is steadily increasing, the line representing speed will be a straight line.
What does a vertical line on a distance time graph indicate?
infinite speed
If a graph shows time on the horizontal axis and speed on the vertical axis a straight horizontal line across the graph would indicate?
constant speed
Why there never can be a vertical line on a speed time graph?
Because - for there to be a vertical line - time would have to stand still !
How is a distance- time graph different than a speed time graph?
The variable plotted along the vertical axis is the distance in the first case, speed in the second. The gradient of (the tangent to) the distance-time graph is the speed while the area under the curve of the speed-time graph is the distance.
Do the slope of the line on a speed-time graph tells the speed?
No. The vertical value of each point (the y-value) tells the speed.
What kind of graph shows an object's speed?
Speed = distance / time A line graph with distance on the vertical axis and time on the horizontal axis could be used to determine speed. The speed would equal the slope of the line. Alternatively, a line graph with distance/time on the vertical axis and time on the horizontal axis would show speed. The acceleration would equal the slope of the line.
A graph has time on the horizontal axis and speed on the vertical axis a straight horizontal line across the graph would indicate what?
The given speed is constant for the given period
If a graph shows time on the horizontal axis and speed on a vertical axis a straight horizontal line across the graph would indicate?
Constant speed ... zero acceleration.
Does the slope of the line on a speed-time graph tell speed?
No. The vertical coordinate tells the speed in this case. The slow is the derivate of the speed, i.e., the acceleration.
