This page will pose a new way of showing acceleration using a graph. Acceleration is the change in speed over time. Usually in a speed-time graph the speed is represented as the change in y (y) or the y-axis. The time is represented as the change in x (x) or the x-axis. The equation of the slope is still defined as the change in y divided by the change in x
Slope = (y/x)
the Acceleration from a speed time graph you must calculate the
slope the same way you would fine the average speed from a
distance-time graph. (click
What does the area under the line mean?
The area under the slope represents the total distance. Using mathematical formulas, you can find the area under the line. Normally shape in which the area can be measured from willl only form a triangle or a square, or both.
still proves the area under a speed-time graph equals the distance
travelled during that time interval.
