Document Summary
A scalar is a physical quantity that has only magnitude and __ direction; a scalar is indicated by an italic letter. (temperature t, distance d, speed v, volume v) are scalars. A vector is a quantity which has both magnitude and _______. (displacement r, velocity v, acceleration a, force f) are vectors. The magnitude of a vector is a ______ quantity. ________ number (with _____!) that describes its size. (the magnitude of velocity v is denoted by v - the speed. ) Distance is a ______ quantity which refers to "how much ground an object has covered" during its motion. Displacement is a _____ quantity which refers to "how far out of place an object is"; it is the object"s change in position: yuan. A vector is a quantity which has both magnitude and direction. It is usually denoted by a boldface letter, a or a letter with an arrow on top . a.
