Question

Is speed a vector quantity?

Answer 1

1. A vector quantity is a physical quantity that requires both magnitude and direction.
2. It is represented by a letter having an arrow over it e.g $\stackrel{\rightharpoonup }{\mathrm{A}}$.
3. Speed is defined as the distance traveled per unit time.
4. It has only magnitude but no direction.
5. Therefore, speed is not a vector quantity instead of this, it is a scalar quantity.
