Question

Which answer accurately describes the difference between speed and velocity?

A.Speed requires distance. Velocity requires direction.
B.Speed is the result of a change in direction. Velocity is the result of a change in acceleration.
C.Gravity affects speed. Gravity does not affect acceleration.
DSpeed measures a change in inertia. Inertia remains the same in velocity.

Answer 1

the answer is A to the question

Answer 2

A.Speed requires distance. Velocity requires direction.

Step-by-step explanation:

The difference between speed and velocity is:

- Speed is a scalar, so it consists only of a magnitude, which is defined as the ratio between the distance covered and the time taken:

`s=(d)/(t)`

So, speed requires distance

- Velocity is a vector, so it requires both a magnitude (which is equal to the speed) and a direction. Therefore, velocity requires a direction.
