Fundamental Scientific laws
What's Newton’s first law?
An object at rest stays at rest and an object in motion stays in motion until acted upon by another force.
What is a system?
A collection of components. Could be biological, social, physical, or abstract.
What are periodic patterns?
Patterns of elements on the periodic table.
What is randomization?
Process of assigning subjects to different groups in a random manor.
What are models?
A simplified representation of a real-world phenomenon.
What is a fundamental Scientific law?
A statement which describes what is happening under specific circumstances.
What is systems science?
A type of science that studies the properties and behaviors of systems.
What are examples of periodic patterns?
Cycles of seasons, phases of the moon, movement of clock hands.
What is adequate power?
When the experiment has enough statistical power.
What are the different types of models?
Physical, conceptual, mathematical, computational
What is the law of universal gravitation?
Every particle attracts every other particle.
What are feedback loops?
Where the output of a system influences its inputs.
What do periodic patterns reveal?
Atomic radius. Ionization energy, and electronegativity
What is an unbiased experiment?
An experiment that attempts to minimize personal beliefs.
How many main types of models are there?
Four
What are Maxwell’s equations?
These are equations which relate to the fundamental laws of electromagnetism.
What are examples of systems?
Biology, physics, engineering, social sciences and earth sciences.
True or False.
There are a definite number of periodic patterns
false
How many key elements are there in an experiment?
Why should you use scientific models?
To simplify complex systems,
Make predications,
Communicate ideas
What is Lorentz’s force law?
The law that describes the direction of an induced current.
Why are system sciences important?
It helps us to not only understand problems but provide the framework for developing solutions.
What was the first periodic pattern?
Chancourtol’s “Telluric Screw”
