If there was no frictional … dhs and legacy ins databaseWebAn ideal pendulum system always contains a stable amount of mechanical energy, that is, the total of kinetic plus potential energy. As the pendulum swings back and forth, the balance between the two types of energy changes constantly. At some points in its swing, the pendulum has more kinetic energy. At other points, it has more potential energy. dhs and nrpWebTotal mechanical energy is defined as. M = K + U. where K = 1 2 m v 2 and U = m g h. No matter which direction the object is moving K must be positive due to the v 2. (I am assuming that mass is also never negative.) Potential energy is also positive because g = 9.8 and height is a distance, which is also non-negative. cincinnati bengals big and tall apparel
