Motion
Who developed the Law of Falling Bodies, and what does it say?
Galileo. It says that all falling objects accelerate at the same rate.
State Newton's first law
An object at rest wants to stay at rest and an object in motion wants to keep moving at the same speed in the same direction unless an outside force acts upon it.
What is inertia?
A property of matter that causes any object to prefer its current state of motion.
What is a hypothesis?
An informed prediction, based on a theory.
What is irreducible complexity?
A system of several interacting parts that contribute to the basic function; removal of any part causes loss of function
What are the SI units for force?
Newtons = N
State Newton's third law
When one object pushes on another with a certain force, the second object pushes back on the first one with equal force.
What is force?
A push or pull.
What is historical science?
How we explain the past. Theories of origins are practicing historical science.
What is a scientific fact?
A scientific statement supported by a great deal of evidence, which is correct so far as we know.
What are the SI units for acceleration?
Meters per second squared = m/s2
What is acceleration? What is the formula used to calculate it?
Changing velocity. acceleration=Force/mass
What is telos?
Greek word meaning goal or end.
Explain natural selection.
An unguided natural process whereby organisms that are better suited to survive and reproduce will tend to pass on their traits to the next generation.
What are the main points of materialism/evolution?
Blind, unguided processes led to all life, laws, and constants of the universe. All species evolved by unguided natural selection acting upon random mutations.
What are the SI units for mass?
kilograms = kg
How does mass affect acceleration?
More mass means less acceleration. They are inversely proportional.
What was Sir Isaac Newton's published work in which he presented his three laws of motion called?
Principia Mathematica, published in 1687.
What is a theory?
A mental model – a conceptual representation of how part of the world works.
What is the difference between micro- and macro-evolution?
Micro-evolution involves small mutations at a species/genus level.
Macro-evolution is the idea that mutation and selection produces new genetic information and jumps to new kinds of organisms at the family level. We have no evidence of this.
State Newton's second law
The acceleration of an object is proportional to the force acting on it. a=F/m
What is velocity? What is the formula?
Speed. velocity=distance/time
Measured in meters/second.
Who first developed the idea of friction?
Galileo
What are the two "books" that point to truth?
The book of nature and the book of scripture.
What are some problems with the theory of evolution?
It can't explain origins.
It relies on mutations bringing about positive changes, but they are usually harmful.
We have no evidence of macro-evolution.
