Physics

Physics is the natural science that studies matter, its basic building blocks, motion and behavior through space and time, and the associated units of energy and force. Physics is one of the most fundamental scientific fields whose main goal is to understand how the universe behaves. Scientists who specialize in the field of physics are called physicists.
