What is a vector?

Back

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

Front

What are the two main components of a vector?

Back

Direction and magnitude.

Front

How do you describe the direction of a vector?

Back

The direction of a vector can be described using angles and cardinal directions (e.g., North, South, East, West).

Front

If a vector is 30 degrees East of North, how would you describe its direction?

Back

The vector is directed 30 degrees away from the North towards the East.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

If Bob walks 2 miles north and then 2 miles west, what is his displacement?

Back

Bob's displacement is 3 miles northwest.

Front

What is the resultant vector?

Back

The resultant vector is the vector that results from adding two or more vectors together.

Front

How do you calculate the resultant of two perpendicular vectors?

Back

Use the Pythagorean theorem: Resultant = √(A² + B²), where A and B are the magnitudes of the two vectors.

Front

What is the effect of a tailwind on the speed of an object?

Back

A tailwind increases the speed of an object moving in the same direction as the wind.

Front

If a Frisbee flies at 1.8 m/s north and encounters a tailwind of 1.2 m/s, what is its speed relative to the ground?

Back

The Frisbee's speed relative to the ground is 3.0 m/s north.
