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©.
You can use different combinations of materials to measure their coefficients of friction. For example, you can use a: 1  Wooden board and a brick to calculate the kinetic coefficient of friction between wood and brick material. 2  Sheet of iron on the board and an iron block to slide down the ramp.3  Sheet of iron with film of oil on it and an iron block to slide down the ramp.hat is the angle where the force of gravity is strong enough to overcome the static friction. By simply knowing the angle or the inclination, you can then calculate the static sliding coefficient of friction between the two materials. You can cover the ramp with various materials to determine different coefficients.
