Question

speed and velocity have same units yet they are different physical quantities. Why?​

Answer 1

Answer:

this is because speed is a scalar quantity whereas velocity is a vector quantity. Speed has no direction, only magnitude whereas velocity has both magnitude as well as direction. That's why there can be a difference in their values.

Answer 2

Explanation:

They both have same units but they are different physical quantities because one of them has direction and other has no direction. Velocity is termed as vector quantity because it has direction with magnitude while speed is called scalar quantity because it only has magnitude and no direction.
