Question

Which statement best explains the difference between velocity and speed?

Answer 1

Answer by mimiwhatsup: B) Velocity is a vector and requires a direction to completely describe it.

Velocity is the speed and direction of an object in motion.

Answer 2

Explanation:

Speed : It is defined as the overall distance travelled by an object divided by total time taken. The mathematical expression is given by :

$s=\dfrac{d}{t}$

It is a scalar quantity i.e. it has only magnitude.

Velocity : It is defined as the total displacement (D) of the particle divided by total time taken. It can be given by :

$v=\dfrac{D}{t}$

It is a vector quantity. It have both magnitude and direction.

Out of given options, the statement that best explains the difference between velocity and speed is (B) i.e. "Velocity is a vector and requires a direction to completely describe it".
