physical scientists examine all the "stuff" or [hypothesis/questions] in the world. they also identify [conclusions] of [observation] and try to figure out what happens to the energy in the universe. the study of physical science makes it possible to understand how everything in the universe works. physical science explains what things are [? made?] of and it also explains [what makes up an object] from planets to dust
