Vector

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

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

Vectors a, b, c are defined as:

a = 2i + 5j; b = i - 3j; c = -3i - j. Answer all correct answers

• a + b = 3i + 8j

• a - b = i + 8j

• a + c = -i + 4j

• c - b = -5i + 6j
