Identify a physical quantity which is NOT a vector.

Correct option is C

The correct answer is (c) Distance.
· Distance is a scalar quantity, meaning it has only magnitude and no direction. It refers to the total path length traveled by an object, regardless of direction.
· Unlike displacement, which is a vector and depends on direction, distance only measures how much ground an object has covered during its motion.
· Scalars, like distance, are completely described by their magnitude.
Additional Information:
· Displacement: A vector quantity that denotes the straight-line distance between an object's starting and ending points, including direction.
· Acceleration: A vector quantity that represents the rate of change of velocity with respect to time, and includes both magnitude and direction.
· Force: A vector quantity, defined as an interaction that changes the motion of an object. It has both magnitude and direction (e.g., Newton’s laws of motion).
