A vector quantity is a quantity which has both magnitude and direction. To fully describe the force acting upon an object, you must describe both its magnitude and direction. Thus, 10 Newtons of force is not a complete description of the force acting on an object. 10 Newtons, downwards is...

Examples of vectors in nature arevelocity, momentum, force,electromagnetic fieldsand weight. A quantity or phenomenon that exhibits magnitude only, with no specific direction, is called a scalar. Examples of scalars include speed, mass, electricalresistanceand hard drive storage capacity. ...
Structured Learning Theory is a radical departure from the current Pavlov-Watson-Skinner system. The latter represents learning change as a scalar quantity: structured learning represents learning gain as a vector quantity. The vector is the difference of loadings on a series of ability, personality ...
