Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the key operations?Vector addition, scalar multiplication, dot product, and cross product
2. What is the historical figures?Key contributors include Hamilton, Gibbs, and Heaviside
3. Why do vectors need both magnitude and direction?Things like speed and force need to know not just how big they are but also which way they go. That’s why vectors carry both size and direction.
4. How do we add two vectors together?You can draw one arrow, then put the tail of the next arrow at the head of the first. The resulting arrow from the start of the first to the end of the second shows the total effect.

Scalar: A quantity that has only magnitude, not direction, such as speed or mass.
Vector Space: An abstract mathematical structure where vectors can be added and scaled.
Dot Product: An operation on two vectors that produces a scalar, often used to find the angle between them.
