Answer: Scalar quantity has magnitude but no direction while a vector quantity has both magnitude and direction.
Explanation:
A scalar quantity is a physical quantity that has magnitude but no direction. Examples are
- temperature, measured in Kelvin
- distance, measured in metres
- speed, measured in metres per second
Vector quantity, on the other hand, is a physical quantity that have both magnitude and direction. Examples are:
- velocity, measured in metres per second (m/s)
- force, measured in newton
- displacement, measured in metres
