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

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

Explanation:

Speed is a scalar quantity. It is the ration of distance and time interval.

Distance is the total path covered by a body.

`speed = (distance)/(time)`

Velocity is a vector quantity. Other than magnitude, direction is important to calculate velocity. It is the ratio of displacement and time interval. Displacement = final position - initial position.

`velocity=(displacement)/(time)`

Thus for calculation, both velocity and speed require time. Velocity requires displacement and speed required distance.
