A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. Examples of vectors in nature arevelocity, momentum, force,electromagnetic fieldsand weight. A quantity or phenomen...
David has taught Honors Physics, AP Physics, IB Physics and general science courses. He has a Masters in Education, and a Bachelors in Physics. A vector is a quantity that has both magnitude (numerical size) and direction. This is the opposite of a scalar, which is a quantity that only...
Physical quantities can be classified as scalar or vector quantities. A scalar quantity is fully described by just its magnitude or size. For example, distance traveled by a body or the mass of a boy. It is sufficient to say the car traveled 20 {eq}km {/eq} or the mass of the boy ...
