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.
Making the world better, one answer at a time. The mass has no effect on the period of the pendulum. The period depends on the maximum speed at the lowest point and the maximum speed only depends on the height at the highest point.
