What is the difference between an elastic and inelastic collision if there are two balls, one stationary and the other projected towards the first one? They are made of the same material.
An elastic collision makes the force of one object transfer completely to the other, and the velocity of the first collider transfers completely to the second, making the first object stationary. An inelastic collision makes the objects have equal velocity, or for a partial inelastic collision, the first object will not lose all of its velocity.

Mathematicians struggled with this problem: 1/3 = 0.33333333 repeating forever. 2/3 = 0.66666666 repeating forever. 3/3 = 1, not 0.99999999 repeating forever. We now know the answer. What is it?
A) Terminating decimals do not apply when the denominator and numerator are equal.
B) They are infinitesimally apart, and so the difference cannot be displayed in our numeric system.
C) The Zero property of integers is closed on division.
D) None of these are the answers, we still have not figured out a solution.
B) They are an infinitesimal apart.
What did Einstein find out about Newton's law of Gravity?
It contradicted his own theory of general relativity.
What is the purpose of a fever?
A fever heats up the temperature of the body and it makes it a less suitable environment for pathogens.
What is the difference between nuclear fusion and nuclear fission?
Nuclear fusion brings atoms together, and nuclear fission tears them apart.

Which of these is not a valid proof?
A) AB is congruent to A'B' so there is a rigid motion that takes AB to A'B'.
B) Triangle ABC is congruent to triangle XYZ because they are both radii of congruent circles.
C) Triangle ACB is congruent to Triangle AXY because there are three congruent angles (AAA).
D) Point E is equidistant from points A and B because it is on the perpendicular bisector of segment AB.
C) This is a false congruence statement because (AAA) does not equal congruence. It equals similarity.
