Vector Quantity

What is Vector Quantity?

A vector quantity is a physical quantity that has both magnitude and direction. Displacement, force, weight, velocity, acceleration, momentum, electric field strength and gravitational field strength are vectors, and two vectors at right angles combine to a resultant of magnitude equal to the square root of the sum of their squares.

This definition is part of the Motion, Forces and Energy chapter in Cambridge O Level Physics.
