Sir Isaac
Newton's 3rd Law states that to every ____________ there is an equal and opposite reaction.
What is action?
True or False? ...A theory is a scientific guess.
What is false?
Even though it is crucial for life as we know it on earth, this force is relatively weak.
What is gravity?
The way things are. It cannot change.
What is truth?
An object in motion stays in motion, and an object at rest stays at rest unless it...
What is acted on by an outside force?
A good scientific theory enables this to be formed and tested.
What is a hypothesis?
EVERY particle of matter exerts this.
What is gravitational force?
These are considered correct as far as we know but may always change.
What are scientific facts?
The equation of Newton's 2nd Law of Motion using words.
What is Force = Mass x Acceleration?
An experimental outcome must be replicated many times before its results can become a new _______.
What is a fact?
Another name for the scientific method.
What is the Cycle of Scientific Enterprise?
This holds for all time and people.
What is truth?
Newton's famous publication that contained his first couple Laws of Motion, centripetal force, and many other theories.
What is Principia?
A test held under controlled conditions.
What is an experiment?
Scientist who designed a torsion balance that, after 80 years, helped determine the precise value of the Universal Gravitational Constant, G.
Who is Henry Cavendish?
(True or false)... Observation is a way both truth and facts may be known.
What is true?
A constant inward force necessary for an object to move in uniform circular motion
What is centripetal force?
A good scientific theory must explain [ALL? or MOST?] related facts?
What is most?
Any particle of matter attracts any other with a force varying indirectly as the square of the distance between them. (In other words, the farther away, the less impact the force has.) What letter represents the distance mentioned?
What is R?
NOTE: Equation is F= G(m1, m2) / R2
A great deal of this supports a scientific fact.
What is evidence?
