Graphical Analysis
Valuable information can be obtained by analyzing graphs.
A. Slope:
1. The slope of a distance-time graph gives the velocity.
(when Y = distance and X = time, slope = Y/X or d/t, which is velocity or speed)
2. The slope of a velocity-time graph gives the acceleration.
(when Y = velocity and X = time, slope = v/t which is acceleration)
B. Area under the curve:
3. The area under the curve of a velocity-time graph gives the displacement.
4. The area under the curve of an acceleration-time graph gives the velocity.
