WebApr 13, 2006 · Rise Time/Fall Time. Rise time refers to the time it takes for the leading edge of a pulse ( voltage or current) to rise from its minimum to its maximum value. Rise time is typically measured from 10% to 90% of the value. Conversely, fall time is the measurement of the time it takes for the pulse to move from the highest value to the lowest value.

"The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 1 = 4.9 m. After two seconds it will have fallen 1/2 × 9.8 × 2 = 19.6 m; and so on. The next-to-last equation becomes grossly inaccurate at great distances. If an object fell 10 000 m to Earth, then the results of both equations differ by only 0.08 %; however, if it fell from geosynchronous orbit, which is 42 164 km, then the difference changes to almost 64 %.
