PHYSICS 1 Flashcards
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.
Scientific method
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.
Hypothesis
The scientific method inclined toward
inquiry, integrity, and humility
Scientific Attitude
A statement about the world that competent observers
who have made a series of observations agree on.
Fact
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 a
principle.
Law
A synthesis of a large body of information that encompasses well-tested and verified hypotheses about certain aspects of the natural world.
Theory
Fake science that pretends to be real science.
Pseudoscience
The property of things to resist changes in motion
Inertia
Every object continues in a state of rest or of uniform speed in a straight line unless acted on by a nonzero net force.
Newton’s first law of motion (the law of inertia)
In the simplest sense, a push or a pull
Force
The vector sum of forces that act on an object
Net Force
An arrow drawn to scale used to represent a vector
quantity
Vector
A quantity that has both magnitude and direction, such as force.
Vector Quantity
A quantity that has magnitude but not direction, such as mass and volume.
Scalar quantity
The net result of a combination of two or more vectors.
Resultant
