Like distance and time, speed and time can also be placed visually on a graph as well. A speed -time graph that has a slope greater than zero shows an object accelerating, graphs that shows a straight means a constant speed is being kept, and a negative slope means the car is decelerating. The steeper the slope, the faster it is either accelerating or decelerating. 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) WENDE |
