Chapter 2, Problem 5A

How does a vector quantity differ from a scalar quantity?

To determine

The difference between a vector quantity and a scalar quantity.

Answer to Problem 5A

Scalar quantity just has magnitude while the vector quantity has both the magnitude as well as the direction.

Explanation of Solution

Introduction:

A vector quantity provides the magnitude of the quantity as well as the direction in which that quantity is being applied.

A scalar quantity just provides the magnitude however the vector quantity provides both the magnitude as well as direction.

For example: speed is a scalar quantity however velocity is a vector quantity.

Conclusion:

Hence, the difference between a vector and a scalar quantity is just because of the direction of a quantity.
