100
Define energy as defined in science.
The ability to do work
100
Define physics.
The study of interactions between matter and energy
100
Describe the difference between physical and chemical properties.
Physical: changing these properties does not change the type of matter.
Chemical: changing these DOES change the type of matter
100
Name 2 ways in which science is limited.
Scope, Assumptions, Bias, and Approximations
200
Who discovered that gravity acts on all objects equally, regardless of mass?
BONUS 200 points: Who incorrectly assumed gravity acts according to mass?
Galileo Galilei;
Aristotle

What's the difference between a law and a theory?
Laws: Theories that stand the test of time and have become accepted.
Theories: a hypothesis that passes the test of many experiments and has the support of other scientists.

Name 5 branches of physics.
Thermodynamics, Acoustics, Modern Dynamics, Classic Mechanics, Astrophysics, Optics, Electromagnetism, Nuclear Physics
200
Is density a physical or a chemical property?
Physical.
200
What books have answers to the questions of the soul?
The Bible and the Book of Mormon
300
What is "an artificial situation that more clearly shows how things happen."
An experiment
300
Define inertia
The tendency of matter to resist change.
300
How does physics relate to other fields of science?
Considered "the foundational science." All other fields of science depend on a proper understanding of physics.
300
What is the difference between mass and weight?
Mass tells the amount of inertia (or matter)
Weight describes the gravitational pull on an object
300
What is bias (in science)?
Human nature often leads one to see and believe what he wants to be true, not necessarily what is actually true.
400
What is the difference between a prediction and a hypothesis?
Prediction: Specific to an experiment
Hypothesis: Generalized guess about a principle
400
This vocabulary term literally means "does not follow"
Non sequitur
400
Rearrange the following equation to answer the question, "How much inertia does an object have?"
m = d*v
400
___________ is an indirect measurement of an object's thermal energy.
Temperature
400
What example of bias did we talk about in class?
John Needham's "spontaneous generation" experiment, vs. Louis Pasteur's experiment.
500
What is the principle of causality?
The law of cause and effect. Events observed in the universe have rational causes; the same cause will always have the same effect.
500
Define equation.
A law of the universe expressed as a mathematical sentence.
A set of symbols summarizing a mathematical relationship between quantities.
500
Albert Einstein said, "The whole of science is nothing more than..."
a refinement in everyday thinking.
500
Give three examples of physical properties, and three examples of chemical properties
Physical: mass, weight, volume, density, temperature, state
Chemical: flammability, oxidation state, toxicity, reactivity, chemical bonding
500
What two reasons are given in the book of why we should study science?
1. The study of science leads us to glorify God.
2. Studying science can benefit man.
