Which one of the following is NOT a scalar quantity?

Correct option is C

​The correct answer is (c) Force

Explanation:

Force is a vector quantity, not a scalar quantity. A vector quantity has both magnitude and direction, while a scalar quantity only has magnitude.

• Force is defined as an interaction that changes the motion of an object and is represented by both magnitude (how strong the force is) and direction (the direction in which the force is applied).
• For example, a force of 10 N acting to the east is a vector because it specifies both the amount and direction.

Information Booster:

• Scalar quantities only have magnitude and do not involve direction. Examples include:
• Time: The amount of duration without direction.
• Speed: The rate of motion without direction, i.e., how fast something is moving, but not the direction.
• Distance: The total path length covered, irrespective of the direction.
• Vector quantities have both magnitude and direction. Examples include:
• Force: Described by magnitude (e.g., 10 N) and direction (e.g., to the east).
• Velocity: Speed with a specific direction.
• Displacement: The shortest path between two points, having both magnitude and direction.

Additional Knowledge:

• Time, Speed, and Distance are scalar quantities.
