Scalar quantities: Scalar quantities are those quantities which have only magnitude but no
direction. Length, mass, time, distance, volume, density, temperature, speed, work, and pressure are few examples of scalar quantities. These can be added, subtracted, multiplied, and divided according to the simple rule of algebra.
Vector quantities: Vector quantities are those quantities which have both magnitudes as well as
direction. Force, displacement, velocity, acceleration, momentum, impulse, and weight are few examples of vector quantities. These can be added, subtracted, or multiplied according to the rule of vector
algebra.
