Motion in a Vertical Circle垂直圆周运动
![]() The motion of a mass on a string in a vertical circle includes a number of mechanical concepts. It must satisfy the constraints of centripetal force to remain in a circle, and must satisfy the demands of conservation of energy as gravitational potential energy is converted to kinetic energy when the mass moves downward. The velocity must increase as the mass moves downward from the top of the circle, subject to the constraints stated. 在竖直圆周上摆动的物体包含了许多力学概念。它必须满足向心力的约束以保持在圆周上,同时必须满足能量守恒的条件,因为当物体向下运动时,重力势能会转化为动能。物体向下运动时,速度必须增加,受上述约束的影响。
