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©.
Answer is NO. If I am walking along a road as I normally do at a constant velocity of 2.5m/s. my velocity is constant, but not zero, and my acceleration is zero. Like wise if I drive my car as I usually do along the highway at a constant velocity of 15m/s, My acceleration is zero. But my velocity is not zero. The converse: In free flight, the acceleration of any object is always 9.81m/sÂ² downwards. It never changes. If I throw a ball up into the air at its highest altitude, as it changes from going up to coming down, the velocity is zero, but the acceleration downwards due to gravity is still as it always is , 9.81m/sÂ³.
