Question

difference between scalar and vector quantity

Answer 1

Scalar quantity is only magnitude whereas vector is both magnitude with direction.for eg velocity is vector quantity whereas speed is scalar quantity

Answer 2

Scalar quantities have a size, but no direction. They are specified by a number (magnitude) and a unit. A few examples of scalar quantities are volume, pressure, distance and time.

Vector quantities have a size as well as a direction. They are specified by a number (magnitude), direction and a unit. Several examples of vector quantities are force, displacement, acceleration and velocity.
