About Science -- Conceptual Physics
The scientific method is used to answer scientific questions The steps include: 1) asking a question; then 2) doing research; then 3) creating a hypothesis; then 4) doing an experiment; then 5) analyzing data; then 6) producing a conclusion
16. Write a short paragraph on the scientific method.
a an educated guess that has yet to be proven by experiment b. a synthesis of a large collection of information that includes guesses. c. close agreement among observations made by competent observers of the same phenomenon d. a guess that has been tested over and over again and repeatedly found to be true.
A hypothesis is
...True
A hypothesis is scientific only if there exists a test for proving it wrong.
... True
In science, an educated guess about the answer is called a hypothesis.
...True
The synthesis of a large body of information that encompasses well-tested and verified hypotheses about a certain aspect of the natural world is known as a scientific theory.
... True
When scientific findings are expressed mathematically, they are easier to verify or disprove by experiment
a. an educated guess that has yet to be proven by experiment. b. a synthesis of a collection of data that includes well-tested guesses. c. close agreement among observations made by competent observers of the same phenomenon. d. a guess that has been tested over and over again and repeatedly found to be true
A scientific fact is
...False
A scientific fact is something that is absolute and unchanging.
a. an educated guess that has yet to be proven by experiment b. a synthesis of a large collection of information including well-tested guesses. c. close agreement among observations made by competent observers of the same phenomenon. d a guess that has been tested over and over again and repeatedly found to be true.
A theory is
a. a hypothesis is testable, whereas a theory is not testable. b. a hypothesis is not testable, whereas a theory is testable. c. a hypothesis can be revised, whereas a theory cannot be revised. d. a hypothesis is a guess that has not been well tested, whereas a theory is a synthesis of well-tested and verified guesses.
One difference between a hypothesis and a theory is that
a. you can better understand science in general if you understand physics. b. the ideas of physics extend into more complex sciences. c. underneath biology is chemistry and underneath chemistry is physics. d. All of the above
Physics is the most basic science because
a. set up one experiment and analyze the results., b) set up many experiments and analyze the results. c. use the results of only those experiments that confmn the hypothesis. d. find the best result and report only that result.
To test a scientific hypothesis, you would
a. Science is a method of answering theoretical questions. b. Technology is a method of solving practical problems . c. Science excludes the human factor. d. A good scientist is influenced by his or her likes and dislikes.

Which of these is a scientific hypothesis?
a. Identifying all the forces acting on a person who is walldng uphill b. Calculating the instantaneous velocity of an accelerating car c. Identifying all the bones in a human body d. Calculating the average density of a person
Which one of the following problems would NOT be considered a part of physics?
a. Recognize a problem. b. Perform experiments to test the predictions. c. Repeat the experiments until the answers match the predictions. d. Formulate a general rule based on the results of the experiments.
