An example of physical science is a course teaching the concepts of energy … Chemists tend to be more interested in the specific properties of different elements and compounds, whereas physicists are concerned with general properties shared by all matter. These latter depend on energy, especially heat, as well as on atoms; hence, there is a strong link between physics and chemistry. Celestial mechanics, the science of the motion of planets and other solid objects within the solar system, was the first testing ground for Newton’s laws of motion and thereby helped to establish the fundamental principles of classical (that is, pre-20th-century) physics.
