Physical science studies the properties of matter and energy, considering the attributes that can be measured. Physics is an empirical science. All that we know of the physical world and the principles that govern its behavior has been learned through the observation of natural phenomena. The ultimate test of any physical theory is its agreement with observations and measurements. Physics is, therefore, essentially a science of measurement. Examples include matter, energy, measurement, and observation.
