Force
What can be defined as anything that has inertia
Matter
Matter can be defined as anythingthat has what
Inertia
The ability to do work
Energy
Changing this does not change the type of matter
Physical properties
When physical properties of matter changes the matter undergoes
Physical change
The amount of matter in an object
Mass
Tha amount af gravitational pull on an object
Weight
The amount of space matter takes up
Volume
How tightly packed the matter is
Density

A special type of mass that existats at extreme temperatures
Plasma
The hotness or coldness of an object is
Temperature
And indirect measurement of an objects thermal energy
Temperatures
Changes they throw and identity of matter
Chemical change
The properties of a substance describing how it changes when reacting with other substances
Chemical change
The study of interactions between matter and energy
Physics
All other fields of science depend on what
A proper understanding of physics
The study of the composition and interaction of matter
Chemistry
The Pisces’s by which scientists investigate the secretes of nature is called
Scientific method
Three steps of the scientific method
Observing
Hypothesizing
Experimenting
A tentative explanation
Hypothesis
An artificial situation
Experiment
Experimented with weight
Galileo Galilei
When an hypothesis has passed many experiments and has been approved be other scientists
Theory
If a theory has enough experiments and stands the test of time
Scientific law
The law of cause and effect
It states: events observed in the universe have rational causes; the same cause will always have the same effect
Principles of casualty
A logic error in which a conclusion is not a logical consequence of the evidence hat the conclusion is supposedly based on
Non sequitur
