Understanding Vectors and Scalars

What are the two main components that define a vector?

• Magnitude and direction

• Magnitude and speed

• Direction and velocity

• Speed and velocity

Which of the following is an example of a direction?

• East

• 10 meters

• 5 kilograms

• 3 liters

How is a vector typically represented in mathematical notation?

• With an arrow above the variable

• With a line under the variable

• With a circle around the variable

• With a dot above the variable

If you tell someone a location is 'half a kilometer north', what type of quantity are you describing?

• Vector

• Scalar

• Speed

• Distance

Why is the number of books on a shelf not considered a vector?

• Because it has no magnitude

• Because it is not a physical quantity

• Because it has no direction

• Because it is not measurable

What is a scalar quantity?

• A quantity with only direction

• A quantity with only magnitude

• A quantity with both magnitude and direction

• A quantity with neither magnitude nor direction

How can the magnitude of a vector be denoted?

• By putting a line under the vector

• By putting a dot above the vector

• By putting two lines on either side of the vector

• By putting a circle around the vector

What makes wind speed and direction a vector quantity?

• It has a speed and a velocity

• It has a velocity and a distance

• It has a magnitude and a direction

• It has a speed and a distance

Which of the following is NOT a vector quantity?

• Velocity

• Displacement

• Force

• Temperature

What is the primary difference between a vector and a scalar?

• Scalars have both magnitude and direction

• Vectors have direction, scalars do not

• Vectors and scalars are the same

• Vectors have magnitude, scalars do not
