What is velocity, because it describes both speed and direction

a. a magnitude

b. a force arrow

c. the same as acceleration

d. a vector

A vector ⇒ answer D

Step-by-step explanation:

* Lets revise some definition to solve the problem

- Speed = distance ÷ time

∵ Distance has no direction

∴ Speed has no direction

∴ Speed is a scalar quantity ⇒ (magnitude only)

- Velocity = displacement ÷ time

∵ Displacement has direction

∴ Velocity has direction

∴ Velocity has magnitude and direction

∵ Any vector has magnitude and direction

∴ Velocity is a vector quantity

∵ Velocity describes both speed (magnitude) and direction

∴ Velocity is a vector
