Solution

The false statement is b. "Speed is the velocity of travel in a specified direction". This is incorrect because speed is a scalar quantity that refers to "how fast an object is moving" regardless of its direction, while velocity is a vector quantity that refers to "the speed of an object in a particular direction".
