Vectors and Scalars

Define Vector.

• Quantity having direction and magnitude (amount).

• Quantity having only magnitude.

• Quantity having only direction.

• A scalar quantity.

Define Scalar.

• Quantity only having magnitude (amount).

• Quantity having both magnitude and direction.

• A unit of force.

• A vector quantity.

What's the difference between scalar and vector?

• Scalar is a quantity only having magnitude (amount), while vector is a quantity having both direction and magnitude (amount).

• Scalar is a quantity having both direction and magnitude, while vector has only magnitude.

• Scalar and vector both have only direction.

• Scalar and vector both have only magnitude.

What is the displacement of the cross-country team if they begin at the school, run 10 miles and finish back at the school?

• 0 miles - they ended where they started.

• 10 miles - the total distance run.

• 20 miles - double the distance run.

• 5 miles - half the distance run.

A vector is a quantity that has both _______ and _________.

Select all that apply.

• direction

• amplitude

• acceleration

• magnitude

• velocity

Which of the following is an application of vectors?

• Measuring temperature

• Calculating distance

• Determining velocity

• Weighing objects

Answer explanation

Vectors are used to represent quantities with both magnitude and direction. Velocity is a vector quantity, as it describes the speed and direction of an object's movement, making it the correct application of vectors among the options.
