- Physics
-
the science concerned with describing the interactions of energy, matter, space, and time; it is especially interested in what fundamental mechanisms underlie every phenomenon
- Quantum mechanics
-
the study of objects smaller than can be seen with a microscope
- Relativity
-
the study of objects moving at speeds greater than about 1% of the speed of light, or of objects being affected by a strong gravitational field
- scientific method
-
a method that typically begins with an observation and question that the scientist will research; next, the scientist typically performs some research about the topic and then devises a hypothesis; then, the scientist will test the hypothesis by performing an experiment; finally, the scientist analyzes the results of the experiment and draws a conclusion
- SI units
-
the international system of units that scientist in most countries have agreed to use; includes units such as meters, liters, and grams
- theory
-
an explanation for patterns in nature that is supported by scientific evidence and verified multiple times by various groups of researchers
- units
-
a standard used for expressing and comparing measurements
