Welcome to Jeopardy! Please raise your hand to answer. An answer must be in the form of a question. Each correct answer is worth five extra credit points. The maximum daily score is 25 points. Each incorrect answer costs five extra credit points. All negative scores will be cancelled at the end of the game (today).

3
A quantity that requires both magnitude and direction for a complete description. What is a vector? The result of adding two vectors. What is the resultant (or sum)? The recommended minimum daily water consumption. What is 50 liters? A quantity that requires only magnitude for a complete description. What is a scalar?

4
In projectile motion, this component of the velocity stays constant. What is the horizontal component? In a diagram, this represents a vector. What is an arrow? This is a projectile traveling fast enough to fall around Earth rather than into it. What is a satellite? Any vector can be resolved into these. What are horizontal and vertical components?

5
In projectile motion, the horizontal acceleration. What is zero? The simplest type of linear motion. What is linear motion with constant speed? A spacecraft circling the Earth is an example of this type of motion. What is projectile motion? Forty five degrees. What is the angle for maximum projectile range?

6
This is the theorem that is helpful for finding the resultant of two vectors. What is the Pythagorean Theorem (a 2 + b 2 = c 2 )? This is the length of the sum of two perpendicular vectors with lengths 3 and 4. What is 5? A stone thrown in the air is an example of this type of motion. What is projectile motion?

7
The name for any object that moves through air or space, acted upon only by gravity. What is a projectile? The diagonal of a parallelogram constructed from two vectors. What is the resultant vector (or vector sum)? This increases an airplane’s ground speed by 41%, but blows it off course by 45 o. What is a crosswind equal to the airplane’s speed?

8
This is another name for nonlinear motion. What is motion along a curved path? In motion, another name for a curved path. What is a trajectory? In a 3,4,5 triangle, the measure of the smallest angle. What is 37 o ? In a 3,4,5 triangle, the side opposite the 53 o angle. What is 4?

9
The cause of shooting stars. What is white hot heating by air friction? Hunger and malnutrition kill this many people each year. What is 10 million? This has reduced global agricultural productivity by 13% in the last half century. What is soil degradation? In 2003, this many people did not have enough to eat. What is 843 million?

10
This organization brought a mobile purification plant to Sri Lanka to provide clean drinking water for almost 20,000 people. What is the German Red Cross?

What is 50,000 years ago? This country has banned duck and goose farming in a bid to head off a mounting bird flu epidemic. What is Vietnam?

12
This chemical, found in fish, can damage the nervous system, affecting intelligence, memory, and behavior. What is mercury? Students from Hong Kong, Finland, and South Korea do best in this school subject. What is mathematics? This country is the largest supplier of foreign oil to the U.S. What is Canada?

13
