Máquina de Atwood

This simple yet economical device provides students with an understanding of linear and angular acceleration and may be used to determine the value of g, the acceleration due to gravity. Consists of 2 low-friction pulleys attached to a support rod which can be mounted to a ring stand. Precise measurement may be made since the pulleys have a low moment of inertia. Requires pulley cord, mass hangers and masses, which are readily available in most classrooms.
