Physics 1 - Chpt 1 Test

In science, an educated guess about the answer to a scientific question is called a hypothesis

• True

• False

A scientific fact is something that is absolute and unchanging.

• True

• False

Which one of the following steps is NOT a part of the scientific method?

• Make a guess about there answer and predict its consequences.

• Formulate a general rule based on the predictions and experimental outcome.

• Perform experiments to test the predictions.

• Repeat the experiments until the answers match the predictions.

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

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

• can be revised, whereas a theory cannot be revised.

• is not testable, whereas a theory is testable

• is testable, whereas a theory in not testable

A hypothesis is scientific if there exists a test that could be used for proving it wrong.

• True

• False

The synthesis of a large collection of information that encompasses well tested and verified hypothesis about certain aspects of the natural world is known as a scientific theory.

• True

• False

When scientific findings are expressed mathematically, they are more difficult to verify or disprove by experiment.

• True

• False
