Vectors - Day 1

Front

What is a vector?

Back

A vector is a quantity that has both direction and magnitude.

Front

What is the direction of the vector <-2, 1>?

Back

153°

Front

What is the direction of the vector <0, 4>?

Back

90°

Front

How do you find the magnitude of a vector given two points?

Back

Use the distance formula: Magnitude = √((x2 - x1)² + (y2 - y1)²).

Front

What is the magnitude of the vector AB with initial point (-3, 1) and terminal point (3, 9)?

Back

10

Front

What is the direction of the vector <2, -5>?

Back

292°

Front

What are the components of a vector?

Back

The components of a vector are its horizontal (x) and vertical (y) values.

Front

How do you represent a vector graphically?

Back

A vector is represented graphically by an arrow, where the length indicates magnitude and the arrowhead indicates direction.

Front

What is the difference between a scalar and a vector?

Back

A scalar has only magnitude, while a vector has both magnitude and direction.

Front

How do you add two vectors graphically?

Back

Place the tail of the second vector at the head of the first vector and draw a new vector from the tail of the first to the head of the second.
