Question

Which of the following is an example of a scalar quantity?

• A. Velocity
• B. Force
• C. Temperature
• D. Displacement

Hint:

Remember that scalar quantities only have magnitude, while vectors have both magnitude and direction.

Answer 1

The Correct Option is C

Step 1: Define Scalar and Vector Quantities
- Scalar: Possesses magnitude only (e.g., mass, temperature).
- Vector: Possesses both magnitude and direction (e.g., velocity, force).

Step 2: Evaluate Each Option
- Velocity: Exhibits magnitude (speed) and direction (e.g., 20 m/s north). Classified as a vector.
- Force: Characterized by magnitude (e.g., 10 N) and direction (e.g., upward). Classified as a vector.
- Temperature: Displays magnitude (e.g., 25°C) but lacks direction. Classified as a scalar.
- Displacement: Exhibits magnitude (e.g., 5 m) and direction (e.g., east). Classified as a vector.

Step 3: Final Determination
Temperature is identified as the sole scalar quantity, aligning with option (3).
