Vectors Mastery Recovery Test

Define distance.

• the relationship between to objects

• the motion of an object between two points in space

• the position of a point in space

• the separation between any two point in space

What is a displacement?

• a change in position

• a change in the origin

• a coordinate system

• two different origin points

What is a vector?

• a type of variable with the same origin point

• a type of variable that includes direction as well as size

• a variable with only positive values and shows direction

• a displacement with no direction and no magnitude

A scalar does not depend on _____.

• position

• distance

• magnitude

• direction

All of the following are scalar values EXCEPT ____.

• distance

• mass

• displacement

• temperature

What is the difference between distance and displacement?

• both show movement, so they are the same

• one is a vector and the other is a scalar

• distance shows direction, displacement does not

• distance shows the origin, displacement does not

What is the "magnitude" of a vector?

• the units of the vector show magnitude

• the sign of the vector shows magnitude

• the length of the vector shows magnitude

• the direction of the vector shows magnitude

Why is a map two dimensional?

• it takes two numbers to uniquely specify any point

• it has two reference points

• it has two directions

• it has two origins
