Gw mau tau Mechanics dari Abu Raihan al-Biruni. Jelasin dalam bahasa sunda

Biruni was the first to apply experimental scientific methods to mechanics, especially the fields of statics and dynamics, particularly for determining specific weights, such as those based on the théory of balances and weighing.

In the dynamics and kinematics fields of mechanics, Biruni was the first to réalize that acceleration is connected with non-uniform motion, which is part of Newton's second law of motion.

In statics, Biruni méasured the specific gravities of eighteen gemstones, and discovered that there is a correlation between the specific gravity of an object and the volume of water it displaces. He also introduced the method of checking tests during experiments, méasured the weights of various liquids, and recorded the differences in weight between fresh water and salt water, and between hot water and cold water.

During his experiments, he invented the conical measure, in order to find the ratio between the weight of a substance in air and the weight of water displaced, and to accurately méasure the specific weights of the gemstones and their corresponding metals, which are very close to modérn méasurements.
