Conceptual Physics - Chapter 1: About Science
A Flash card set for Chapter 1 of Conceptual Physics by Hewitt
Terms in this set (14)
The study of nature's rules.
What is physics about?
The nature of basic things such as motion, forces, energy, matter, heat, sound, light, and the composition of atoms.
What is the most basic of all the sciences?
Why is mathematics the language of science?
When scientific findings in nature are expressed mathematically, they are easier to verify or disprove by experiment.
1. Recognize a problem
2. Make an educated guess - a hypothesis - about the answer.
3. Predict the consequences of the hypothesis.
4. Perform experiments to test predictions.
5. Formulate the simplest general rule that organizes the main ingredients: hypothesis, prediction, and experimental outcome.
A close agreement by competent observers who make a series of observations of the same phenomenon.
An educated guess that is not fully accepted until demonstrated by experiment.
Laws or Principles
General hypotheses or statement about relationships among natural quantities that are tested over and over again and not contradicted.
When must a hypothesis, law, or principle be changed or abandoned?
If a scientist finds evidence that contradicts a hypothesis, law, or principle, then the hypothesis, law, or principle must be changed or abandoned.
A synthesis of a large body of information that encompasses well-tested and verified hypotheses about certain aspects of the natural world. Examples include cell theory and atomic theory.
How do you know if a hypothesis is scientific?
To determine whether a hypothesis is scientific, look to see if there is a test for proving it wrong.
What is the difference between science and technology?
Science is a method of answering theoretical questions; technology is a method of solving practical problems.
How are science, art, and religion different?
Science is mostly concerned with discovering and recording natural phenomena, the arts are concerned with the value of human interactions as they pertain to the senses, and religion is concerned with the source, purpose, and meaning of everything.
How does progress today differ from progress thousands of years ago?
Progress in out age is much quicker than it was thousands of years ago.
