Question

Average velocity is different than average speed because calculating average velocity involves what?

Answer 1

Two things that aren't involved in speed: -- the straight-line distance between the start- and end- points. -- the direction from start-point to end-point.

Answer 2

The correct answer to the question is: Direction

EXPLANATION:

The average velocity of a body is defined as the rate of change of displacement.

We know that displacement is a vector quantity. Hence, it has magnitude as well as direction for its specification.

On the other hand, the average speed of a body is defined as the rate of change of distance travelled. Hence, the average speed of a body is a scalar quantity. It means that it has only magnitude.

Hence, during the calculation of average velocity,we have to think of its direction.
