Physics 100 Chapter 1( Physics fundamentals)

Draw a conclusion

Formulate the simplest general rule that organizes the three main ingredients. hypothesis, predicted effects, and experimental findings.

Scientific Method

Orderly method for gaining, organizing, and applying new knowledge.

Predict

Predict consequences of the hypothesis.

Science

is the body of the knowledge that describes the order within nature and the causes of that other, also it's on going human activity that represents the collective efforts, findings and wisdom of the human race. an activity that is dedicated to gathering knowledge about the world and organizing and condensing it into testable laws and theories.

Law

A general hypothesis or statement about the relationship of natural quantities that has been tested over and over again and has not been contradicted. Also known as principle.

Fact

A phenomenon about which competent observers who have made a series of observations are in agreement.

Theory

A synthesis of a large body of information that encompasses well-tested and verified hypotheses about certain aspects of the natural world.

Which of the following is a scientific hypothesis? A. Tides are caused by the moon. B. Chlorophyll makes grass green. C. Earth rotates about it's axis because living things need an alternation of light and darkness. D. There are parts of the universe that will never be found by humans. E. None of the above.

A. Tides are caused by the moon. B. Chlorophyll makes grass green.

Hypothesis

An educated guess; a reasonable explanation of an observation or experimental result that is not fully accepted as factual until tested over and over again by experiment.

E. Understood the physical and biological worlds.

Pseudoscience

Fake science that pretends to be real science.

Question

Make an educated guess a hypothesis that might resolve the puzzle

Scientific Methods Steps

Observe Question Predict Test predictions Draw a conclusion

Observe

Observe Closely observe the physical world about you. Recognize a question or a puzzle such as an unexplained observation.

Scientific Method

Principles and procedures for the systematic pursuit of knowledge involving the recognition and formulation of a problem, the collection of data through observation and experiment, and the formulation and testing of hypotheses.

Model

Representation of an idea created to make the idea more understandable.

Which of the following is considered a science? a. Astrology b. Astronomy c. Creationism d. Extrasensory perception e. Study of crop circles

b. Astronomy

Test Prediction

do experiments or make calculations to test the predictions.
