Vaginal rugae are believed to yield important clues as to the str\uctural integrity and hormonal status of the lower genital tract. We have demonstrated that use of a 10 cm visual analog scale renders reliable intra- and interexaminer results.
OBJECTIVE: To study the motion of an object traveling up and down a ramp in the absence of friction and drag forces. To measure the acceleration of such an object and see how the acceleration depends on the ramp angle.THEORY: If an object falls straight down and air resistance is small, we found in the last experiment that it accelerates down at 9.8 m/s2.an you think of different ways that the acceleration, a, might depend on the angle, ï±ï¿ï ï Remember that we do expect. a = 0 m/s2 at ï±ï ï½ï 0o and a = 9.8 m/s2 at ï±ï ï½ï 90o. a(() = ??? In this experiment we will try to come up with an empirical (based on experimental data rather than theory) relationship for a(()ï©.
Specifically, gravity increases a falling object's velocity by 9.8 meters per second (m/s) with every passing second. (Whereas velocity is measured in m/s, acceleration is measured in meters per second squared, or m/s 2 .) How does this constant acceleration affect the distance that an object travels over time?In this experiment you will roll a marble down a ramp to find out. Mark the distance traveled on the ramp each time. 2  Using a longer ramp, how does gravity appear to affect the velocity and acceleration of a marble as it rolls downhill? 3  Extra: Try repeating this activity with different balls, such as a rubber ball, large metal ball bearing, ping pong ball, etc.
