Shoulder pain is any pain in or around the shoulder joint. When tendons become trapped under the acromion, the rigid bony arch of the shoulder blade, it can cause shoulder pain called impingement syndrome.
The period for a simple pendulum does not depend on the mass or the initial anglular displacement, but depends only on the length L of the string and the value of the gravitational field strength g, according to The mpeg movie at left (39.5 kB) shows two pendula, with different lengths.
26 apr 2017 note that this equation does not include terms for the mass of the pendulum or the angle it swings through. Logt log(2 ) 12(logl logg)so, for a variation l we have t the mass of pendulum's bob does not affect period. I think that the length of string directly affects period one oscillation.
