Either of these two words, both starting with the letter "r" is what a good scientific experiment should be.
What is repeatable or replicable?
100
This is the base SI unit of mass.
What is the kilogram (kg)?
100
This is 3001 in scientific notation.
What is 3.001 x 10^3?
100
Suppose you are practicing your pitching on the team's train traveling to a game. This is the best frame of reference for measuring your pitch speed in that situation.
What is the train (or relative to the train)?
100
If the slope of a distance-time graph is negative, this is what the object must be doing.
What is moving backwards?
200
If every day you record the temperature in the same location at noon, these are the responding variable and the manipulated variable.
What are the temperature and the day?
200
This is a derived SI unit of acceleration.
What is a meter-per-second-squared?
200
This is 2.5 x 10^2 in standard notation.
What is 250?
200
If we add a displacement to the east with a smaller displacement to the west, the resulting displacement vector will point in this direction.
What is to the east?
200
This is calculated by dividing the total distance an object travels by the total time it takes to travel.
What is average speed (or velocity)?
300
A laser range finder gives a distance with five significant figures and is within 0.001 m of the actual distance. A tape measure gives a distance with three significant figures and is within 0.01 m of the actual distance. This is the more accurate instrument.
What is the laser range finder?
300
This is the prefix meaning "hundredth"
What is "centi-"?
300
This is 1.04 x 10^-3 in standard notation.
What is 0.00104?
300
It is 3860 km from San Francisco Airport (SFO) to Honolulu Airport (HNL). This is your displacement for a round trip from SFO to HNL.
What is zero?
300
If you ride your bike 3 km north, then 4 km east, and finally 5 km southwest, this is the distance you have traveled.
What is 12 km?
400
The more students carrying Mr. Tropp's throne, the less weight each one needs to support. So the number of students and the weight each one needs to support are related this way.
What is inversely proportional?
400
This is the symbol for average speed in an equation.
What is v-bar (v with a bar over it)?
400
This is the number of significant figures in 1000.0
What is 5?
400
This is what we calculate when we divide the displacement of a moving object by the time it takes for that displacement to occur.
What is velocity?
400
If you run at 7 km/h for 2 h and then walk at 4 km/h for 4 h, this is your average speed for the trip.
What is 5 km/h?
500
This is what we call the checking of a scientist's work by other scientists before it is approved for publication?
What is peer review?
500
This is a derived SI unit of area.
What is a [meter, centimeter, millimeter, kilometer, etc.] SQUARED?
500
This is the product of 12 and 3 with the correct number of significant figures.
What is 40?
500
This is the rate at which an object's velocity is changing.
What is acceleration?
500
This is the acceleration experienced by an object in free fall near the surface of the Earth.
