Vectors Quiz Review

Vector is a quantity with:

• magnitude and direction

• magnitude

• direction

• none of the above

When adding two vectors graphically, a+b=c. Does b+a produce the same resultant vector c?

• Yes, two vectors added together always produce the same resultant vector

• No, because order matters

• Yes, but c will be pointing in the opposite direction

• No, because you can't add two vectors

If v =〈a,b〉, then a is the ___________ component of v.

• vertical
• horizontal
• parallel
• slope

When subtracting two vectors, a-b=c. Does b-a produce the same resultant vector c?

• Yes, two vectors subtracted together always produce the same resultant vector

• No, because order matters

• Yes, but c will be pointing in the opposite direction

• No, because you can't subtract two vectors

When adding vectors graphically, the magnitude of the resultant vector is represented

• the length of the vector drawn

• the arrow head of the vector drawn

• both of the above

• none of the above

What is the sum of a vector addition problem called?

• components

• scalar

• resultant

• magnitude
