200
Give an example of a scalar.
What is speed/ distance.
200
Define distance.
It is the total measurement of how far the object moved during the trip.
200
How do you find the sine of an angle?
What is Opposite/ Hypotenuse.
200

What is 4.6 hours.
300
How many kilometers is equivalent to 3000 meters?
What is 3 kilometers.
300
Scalars just have ________________.
What is magnitude/size.
300
Calculate the displacement of an object that began at 0 km and ended at 70 km.
What is 70 km.
300
This is the longest leg of a triangle. It is represented by "C" in the Pythagorean Theorem.
What is the hypotenuse.
300
How far will an airplane travel if it is moving 200 km/h east for 3.5 hours? Is this distance or displacement?
What is 700 km. Displacement.
400
How many DECAmeters is equal to 12,300 centimeters?
What is 12.3 DECAmeters.
400
Vectors have magnitude AND _______________.
What is direction.
400
Calculate the displacement of an object that began at 5km and ended at 65 km.
What is 60 kilometers.
400
What equation would you use to solve for a missing side in a triangle?
What is A squared + B squared = C squared.
400
Can an object be moving for 10 seconds and have a velocity of zero? Why or why not?
What is: it depends on the displacement. It the object has a displacement of zero, it will have a velocity of zero.
500
FIFTY milligrams is equal to how many KILOgrams?
What is 0.00005 KILOgrams.
500
If a car travels 50 km west, would you use distance or displacement to solve? Why?
What is displacement. Because WEST indicates that it is a vector quantity.
500
Calculate the distance and displacement for an object that moved 10 meters NORTH, rolled 3 meters SOUTH, and then rolled another 8 meters NORTH.
The displacement is 15 meters NORTH.
The distance is 21 meters.
500
CALCULATE the length of the opposite side of the triangle if the adjacent side is 10 meters and the angle is 45 degrees (the tangent of 45 degrees = 1)
What is 10 meters.
500
EXPLAIN: What does it mean that speed is relative.
What is the relationship between objects in a system. You must look at the reference point- the object with zero velocity/speed- and compare the speed of the other moving objects in relation to it.
