They are discovered by observation and experiment, and by making inferences from what we observe or from the results of our experiments. They are correct as far as we know, but we may change them as new information becomes known.
What are scientific facts?
100
The base units of the MKS system.
What are meter, kilogram, and second?
100
The effect of this property is that a material object will always resist changes to its "state of motion."
What is inertia?
100
A Newton-Meter -- a unit for work.
What is a Joule (J)?
100
It's the c in E=mc^2.
What is the speed of light?
200
A mental model developed using scientific processes of experiment, observations, and logical thinking.
What is a theory?
200
They are limitations inherent in making measurements; and the number of significant digits included when making a measurement reflect them.
What are accuracy and precision?
200
For every action force, there is an equal and opposite reaction force.
What is Newton's Third Law?
200
The energy an object possesses because it in motion.
What is kinetic energy?
200
It means 10^3.
What is "kilo?"
300
Repeat the work.
What is the "last step" in the scientific method?
300
The change in velocity divided by the change in time.
What is acceleration?
300
It is the equation that embodies Newton's Second Law.
What is a = F/m (or F=ma)?
300
In the "energy trail," it is typically the form of the energy in the first step.
What is nuclear energy?
300
It is how many feet are in a mile.
What is 5280?
400
The three kinds of variables in scientific experiments.
What are lurking, explanatory, and response variables?
400
The scientists most cited as the fathers of the heliocentric model. (Hint -- You need at least three of the four).
Who are Copernicus, Brahe, Kepler, Galileo?
400
The common unit for force -- a Newton -- represented in base MKS units.
What is 1 kg * m / s^2? (What is a kilogram-meter-per-second-squared?)
400
It's energy that we say is "lost" in a process.
What is energy converted into a non-useful form, such as heat?
400
It's the equation that explains why mass should be considered a form that energy can take.
What is Einstein's equation of mass-energy equivalence (E=mc^2)?
500
A major branch of philosophy that studies what we can know and how we know it.
What is Epistemology?
500
The two types of motion we have studied so far in this class.
What are motion without acceleration and motion with uniform/constant acceleration?
500
The force with which gravity is pulling on an object.
What is weight?
500
It says that energy can be neither created nor destroyed, only changed in form.
