100What is mass?
The kilogram is the proper SI unit for this quantity.

100What is formula for average speed?
distance divided by time

100What is a scalar quantity?
This is anything which has no direction.

100What is 2 meters/second?
This is the velocity of an object which has a displacement of 10 meters over a time of 5 seconds.

100What is 16.67 meters / second?
This is how fast Ms. Clanton is moving using the proper SI units if she travels 15,000 meters from her house to the store and 15,000 meters back home again in 30 minutes.

200What is 1000, or 10^3?
The kilo is the SI prefix for this.

200What is formula for average acceleration?
change in velocity divided by time

200What is a vector quantity?
This is anything which has a direction.

200What is 2.78 meters/second?
This is the speed in SI of an object which moves 10 kilometers east in 1 hour.

200What is the Leaning Tower of Pisa?
This is the building where legend says that Galileo performed his experiments which determined that all objects fall at the same rate regardless of mass.

300What is acceleration?
The proper SI set of units for this quantity is meters/second/second.

300What is the formula for displacement?
final position minus initial position

300What is distance?
This is defined as the scalar quantity for path length.

300What is ZERO?
This is the acceleration of an object which moves at 30 m/s for 5 seconds.

300What is an inclined plane?
This is the major piece of equipment Galileo used to find a mathematical relationship among distance, acceleration, and time.

400What is 1/1,000,000?
The SI prefix micro means this.

400What is formula for average velocity?
displacement divided by time

400What is displacement?
This is the vector quantity equal to final position minus initial position.

400What is 20 m/s?
This is the speed of an object 2 seconds after it is dropped from rest near the surface of the earth, assuming no wind resistance acts on the object.

400What is 9.8 m/s/s (10 m/s/s) downward?
This is the acceleration of an object which is thrown upwards at the very top of its path, assuming no wind resistance acts on the object.

500What is the meter?
This is the proper SI unit for position, distance, or displacement.

500What is the formula for average velocity?
final position minus initial position all divided by time

500What is a vector quantity?
This is the kind of quantity you get when you multiply a scalar quantity by a vector quantity.

500What is 15 m/s upward?
This is the velocity of an object 2 seconds after it is thrown vertically upward at an initial speed of 35 m/s at or near the surface of the earth, assuming no wind resistance acts on the object.

500What is 10 m/s?
An object moving straight upwards slows down this much each second.
