Question

Which explains the information needed to calculate speed and velocity? both require the total distance, but velocity also requires time and displacement. both require time, but velocity requires displacement and speed requires distance. speed requires displacement, while velocity requires distance. speed does not require time, while velocity does require time?

Answer 1

Both require time, but velocity requires displacement and speed requires distance.

Answer 2

The correct statement is:
Both require time, but velocity requires displacement and speed requires distance.

Velocity is a vector quantity, which means it has both magnitude and direction. Thus, in order to calculate it, another vector quantity is used, which is displacement. On the other hand, speed is a scalar quantity, meaning it has only magnitude and is calculated using the scalar quantity distance.
