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©.
However the component of the weight of the block normal to the incline is decreasing as you increase the angle and hence the Frictional Force = N*(mu) = [WCos(alpha)]*(mu) where 'mu' = Coef of Friction and alpha = angle of incline of plane.(normal) * Î¼. Normal force is the force perpendicular to a surface. When the wooden block is on the ramp, the friction force is between the block and the ramp. Not all the weight from the block is directed perpendicular to the ramp. The blocks weight acts at an angle to the ramp.
