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: Has only magnitude (e.g., mass, temperature).
- Vector: Has magnitude and direction (e.g., velocity, force).

Step 2: Analyze each option
- Velocity: Has magnitude (speed) and direction (e.g., 20 m/s north). Vector.
- Force: Has magnitude (e.g., 10 N) and direction (e.g., upward). Vector.
- Temperature: Has magnitude (e.g., 25°C) but no direction. Scalar.
- Displacement: Has magnitude (e.g., 5 m) and direction (e.g., east). Vector.

Step 3: Conclusion
Temperature is the only scalar quantity, matching option (3).
