Question

Which explains the information needed to calculate speed and velocity?

A. Both require the total distance, but velocity also requires time and displacement.
B. Both require time, but velocity requires displacement and speed requires distance.
C. Speed requires displacement, while velocity requires distance.
D. Speed does not require time, while velocity does require time.

Answer 1

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

Step-by-step explanation:

Edge.

Answer 2

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

Step-by-step explanation:

Velocity is a vector quantity and speed is a scalar variable.

To find the velocity;

Velocity =
`(displacement)/(time)`

Displacement is the distance covered along a specific direction.

So, the way displacement changes with time is the velocity. Also, the directional attribute is important in describing velocity

Now,

Speed is the distance traveled per unit of time;

Speed =
`(distance)/(time)`

No directional attribute involved
