Question

. Which of the following is a vector describing how fast an object moves over a long time interval?. . average speed. instantaneous velocity. instantaneous speed. average velocity

Answer 1

"Average velocity" is the vector among the choices given in the question that describes how fast an object moves over a long time interval. The correct option among all the options that are given in the question is the last option or the fourth option. I hope the answer has helped you.

Answer 2

By definition we have to:

The average velocity is that velocity in a given time interval. It is calculated by dividing the displacement by the elapsed time, according to the following formula:

$v = \frac{xf - xi}{tf - ti}$

We must remember that the average velocity is a vector. Therefore, it has magnitude and direction.

Answer:

The following is a vector describing how fast an object moves over a long time interval:

average velocity
