Introduction: The Nature of Science and Physics
The four fundamental units we will use in this text are the meter (for length), the kilogram (for mass), the second (for time), and the ampere (for electric current).
Practice this chapterThe four fundamental units we will use in this text are the meter (for length), the kilogram (for mass), the second (for time), and the ampere (for electric current). All units can be expressed as combinations of four fundamental units
Physics is the most basic of the sciences, concerning itself with energy, matter, space and time, and their interactions Scientific laws and theories express the general truths of nature and the body of knowledge they encompass.
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. law — a description, using concise language or a mathematical formula, a generalized pattern in nature that is supported by scientific evidence and repeated experiments. fundamental units — units that can only be expressed relative to the procedure used to measure them. units — a standard used for expressing and comparing measurements.
Worked example
What does “physics” mean in Introduction: The Nature of Science and Physics?
- 1Use the wording this chapter gives for physics.
- 2The book says: the science concerned with describing the interactions of energy, matter, space, and time; it is especially interested in what fundamental mechanisms underlie every phenomenon.
- 3Do not use the meaning of law. That term means a description, using concise language or a mathematical formula, a generalized pattern in nature that is supported by scientific evidence and repeated experiments.
Result: the science concerned with describing the interactions of energy, matter, space, and time; it is especially interested in what fundamental mechanisms underlie every phenomenon
Why. That is the meaning this chapter gives for physics.
Do not swap physics and law. physics means the science concerned with describing the interactions of energy, matter, space, and time; it is especially interested in what fundamental mechanisms underlie every phenomenon. law means a description, using concise language or a mathematical formula, a generalized pattern in nature that is supported by scientific evidence and repeated experiments.
