What is Tangential Velocity - Trigonometry Online Tutoring

What is Tangential Velocity - Trigonometry Online Tutoring An object moving in a circular path has velocity which is directed towards the tangent drawn at a specific point on the circle at a certain instant of time. This velocity is known as the tangential velocity. This velocity is the objects instantaneous velocity at a particular instant of time, when the object is moving in the circular motion. The speed of the object with which it is moving on a circular path is considered as the magnitude of the tangential velocity; however its direction is along the tangent drawn at that particular point. Example 1: An object travels on a circular track of radius 10m. What is the tangential velocity of the object, if it takes 6secs to complete one circular rotation around the track? Tangential velocity, vt = (Distance travelled)/ (Time taken) Distance travelled on the circular track = Circumference of the circle = 2r This implies: Distance, d = 2 * * 10 = 20 meters. Time, t = 6secs Tangential velocity, vt = 20/6 = 10.47m/sec Example 2: A car takes 9secs to complete one circular rotation on a circular path. What is the tangential velocity of the car, if the radius of the circular path is 8m? Tangential velocity, vt = (Distance travelled)/ (Time taken) Distance travelled on the circular track = Circumference of the circle = 2r This implies: Distance, d = 2 * * 8m = 16 meters. Time, t = 9secs Tangential velocity, vt = 16/9 = 5.58m/sec

Singing and Athleticism Whats the Link

Singing and Athleticism Whats the Link Suzy S. When youre a singer and a performer, taking care of your vocal cords is essential to staying on top of your game. How much does staying in shape physically factor into that? Here, Gainesville, FL vocal teacher Anna F. tackles the question Stop a random passerby on the street, and ask them to describe an opera singer. The typical response includes horns, a breastplate, braids, and beneath all of the accoutrements an overweight singer. It is important for singers of all ages to understand the benefits of keeping both vocally AND physically healthy. From a hiring perspective, the importance of being in shape cannot be overemphasized. Opera productions have moved away from park-and-bark stagings, and are now moving to compete with the intense, dramatic acting of straight theater. Simply put, a singer must have the physical capability to easily get themselves around a stage (this goes double, if not triple for a singer with Broadway aspirations). In addition, many of opera’s most cherished heroines are supposed to be young girls, and/or even deathly ill (Mimi, Violetta, I’m looking at you). But being physically active and athletic is important beyond the stage. I firmly believe that there is a direct correlation between good health and good singing. A few years ago I (unwillingly) picked up running. Between grad school, an assistantship, a serving job, and rehearsals, I didn’t have time to go to a gym, so running seemed the best option for losing some weight. And I will swear on my life that the controlled breathing necessary to a successful run (and not feeling like you’re going to pass out at any given moment) contributed to my increased understanding and grasp of breath control in singing. All of a sudden it made sense â€" you couldn’t blow all your air right away and expect to make it through the phrase, let alone the next half-mile. While this seems fairly common sense, the idea is fairly abstract until you’re bent over, gasping for air and wishing you weren’t still two miles from home. I give all of my students the same advice: eat well, drink water, get plenty of sleep, and stay active. Nightly walks, running a few times a week, yoga in the mornings; pick one and stick with it! It will pay off in the long run. Anna F. teaches singing, Broadway singing, opera voice, speaking voice and acting lessons to students in Gainesville, FL.
