Physic Exam Review 1
Physics is the most basic science because
(you can better understand science in general if you understand physics.the ideas of physics extend into more complex sciences.underneath biology is chemistry and underneath chemistry is physics.)All of the above
A full scientific theory must be developed before an experiment can be performed.
False
A scientific fact is something that is absolute and unchanging.
False
The scientific method has little to do with the technology that we enjoy today.
False
The scientific method which scientists actually use is a neat, orderly series of steps.
False
Theories can be promoted to laws.
False
Which one of the following steps is NOT part of the scientific method?
Repeat the experiments until the answers match the predictions.
A hypothesis is scientific if there exists a test for proving it wrong.
True
A theory can be used to help find the conclusion of an experiment.
True
Experiments can validate a scientific theory.
True
If a theory comes to be correct in every way, it is considered true until proven otherwise.
True
In general, a single experiment cannot disprove all the parts of a scientific theory.
True
The scientific method is relatively new, and people have been using it regularly for less than 500 years.
True
Theory is a way to mathematically describe a phenomenon observed in an experiment.
True
When scientific findings are expressed mathematically, they are easier to verify or disprove by experiment.
True
A scientific theory
can make predictions.
A scientific experiment
is a controlled test.
The difference between a hypothesis and a theory is that a hypothesis
is a guess that has not been well-tested, whereas a theory is a synthesis of well-tested and verified guesses.
The scientific method is powerful because
it allows people to test their predictions.
