Who is Mark?
This law explains why the downward force of a rocket engine causes the rocket to accelerate upward.
What is Newton's Third Law?
This type of energy is related to an object's location in the gravitational field.

3. Analyzed experiments for lurking variables
4. Other possible?
State the velocity equation.
What is velocity equals distance divided by time? (Or v = d/t)
State the relationship between distance and the force of gravity.
What is "as distance increases, gravity decreases" OR "inverse?"
In this type of system, energy is never lost due to friction.
What is an ideal system?
Responsible for the universal law of gravitation.
Who was Isaac Newton?
A train accelerates from 1.5 m/s to 14.5 m/s in 11s. Find its acceleration.
What is 1.2 m/(s^2) ?
This is the principle of causality.
What is, causes have proportional effects?
This is the acceleration equation.
What is acceleration equals final velocity minus initial velocity divided by time? Or:
a = (v_f-v_i)/t
This law explains why a soccer ball moves in the direction in which it was kicked.
What is Newton's Second Law?
This form of energy is not possessed and is used to move another object.
What is work?
Developed three laws of planetary motion.
Who was Johannes Kepler?
A force of 102 N is applied to a box, causing an acceleration of 3.33 m/s2. Find the mass of the box.
What is 30.6 kg?
How the law of conservation of energy demonstrates the principle of causality, in one sentence.
What is, "the energy is converted from energy of a different source with an equivalent amount?" (Or something similar)
Determine the statement(s) that are evident truths:
1. Principle of Causality
2. Law of conservation of energy
3. Men have noses
4. The Word became flesh
What is (1) Principle of Causality and (3) men have noses?
State the equation relating work and force.
What is Work = force times distance? OR W = Fd
This type of energy is released when mass is converted into energy?
What is nuclear energy?
Insisted that Copernicus' model must be taken as true, did not accept elliptical orbits.
Who was Galileo?

Determine which of the following words/phrases apply to scientific facts:
1) provisional
2) truth claims
3) complete
4) opinions
What is (1) provisional and (2) truth claims?
This type of energy is related to an object's motion.
What is kinetic energy?
This law explains why the work required to lift an object is equal to its weight.
What is Newton's First Law?
This person observed the Jupiter-Saturn conjunction in 1563.
Who was Tycho Brahe?
A 1.60 kg ball is thrown straight up with a velocity of 2.11 m/s. How high does it go before coming to a stop?
What is 0.227 m?
How Copernicus' model did not immediately replace Ptolemy's model, in one sentence.
What is, it did not make more accurate predictions? (Or something similar. Remember, it is good that it did not immediately replace the older model!)
