Answer the following question given this paragraph: 

Physical science, in turn, can be divided into chemistry and physics. Chemistry is the study of matter and energy at the scale of atoms and molecules. For example, the synthetic fibers in the swimmer’s suit were created in labs by chemists. Physics is the study of matter and energy at all scales—from the tiniest particles of matter to the entire universe. Knowledge of several important physics concepts—such as motion and forces—contributed to the design of the swimmer’s suit.


Q: The physical sciences can be divided into physics and what other science?


A:
chemistry
