Newton's cradle Newton's cradle Newton’s cradle is a device that demonstrates conservation of momentum and energy using a series of swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward. The last sphere swings back and strikes the still nearly stationary spheres, repeating the effect in the opposite direction. The device is named after 17th-century English scientist Sir Isaac Newton. It is also known as Newton's balls or Executive Ball Clicker. A typical Newton's cradle consists of a series of identically sized

The Chinese government donated 500 solar water heaters to be installed in the liberated areas in South Lebanon. The Lebanese Center for Energy Conservation (LCEC) was assigned by the Ministry of Energy and Water (MEW) to support its installation both technically and financially. The workload consisted of handling all project logistics, hosting Chinese experts to conduct an intensive training workshop, assisting in the selection of beneficiaries. In addition to the above, a sum of 112,500 USD was
