Definition: In physics, an arrowhead is a type of curve or profile used to represent a vector quantity. It is typically represented with a sharp or curved line at the end of the arrowhead, and it is often used in formulas to indicate direction or magnitude.
For example, in the formula for velocity, where "v" represents the speed of an object, the arrowhead would be drawn as a curve that indicates the direction of motion. This curve could be defined by specifying the slope of the line
