Question

Which statement is true? Speed is a scalar quantity and velocity is a vector quantity. Speed and velocity are both scalar quantities. Speed and velocity are both vector quantities. Speed is a vector quantity and velocity is a scalar quantity. Speed and velocity are neither a scalar quantity nor a vector quantity.

Answer 1

Speed is a scalar and velocity is a vector.

Answer 2

Speed is a scalar quantity and velocity is a vector quantity.

Step-by-step explanation:

Speed ​​is a scalar magnitude since it relates the distance traveled with time. Meanwhile, velocity is a vector magnitude since it relates the change of the position vector with time, that is, it involves the direction and direction of motion. Therefore, speed is the magnitude of velocity vector.
