Answer : The correct option is, Speed is a scalar quantity and velocity is a vector quantity.
Explanation :
Speed : It is defined as the distance traveled by the object per unit time.
It is a scalar quantity because it does not depends on the direction of an object but it depends on the magnitude of the object. The unit of speed is, meter/second or m/s.
For example : The speed is written as, 44 m/s.
Velocity : It is defined a the displacement of an object with respect to the time.
It is a vector quantity because it depends on both direction and as well as on magnitude of the object. The unit of velocity is, meter/second or m/s.
For example : The velocity is written as, 44 m/s north.
Hence, the correct option is, Speed is a scalar quantity and velocity is a vector quantity.
