Question

what is the representation of the momentum vector? (1 point)
○ a number
○ a dot
○ an arrow
○ a straight line

Explanation:

Momentum is a vector quantity, which has both magnitude and direction. Vectors are typically represented by arrows, where the length of the arrow represents the magnitude and the direction of the arrow represents the direction of the vector. A number represents a scalar (magnitude only), a dot is a point (not a vector representation), and a straight line doesn't indicate direction like a vector needs. So the momentum vector is represented by an arrow.

Answer:

C. an arrow
