The answer can’t be unambiguous. There is no one nominated father of physics in history because different people could be granted this title.
For example, in the late Middle Ages, the father of physics was Galileo Galilei, an Italian astronomer. He became a precursor of the classical mechanics of Sir Isaac Newton. The latter person is also known as a progenitor of physics but in his times. In the 20th century, Albert Einstein became the most outstanding star of this science and received this title because of his theories of special relativity.
Therefore, we can’t name the only father of physics because there were a few of them in Western cultures.
