Correct answer and explanation

Correct answer: Speed

Explanation: āœ… Correct Answer: (D) Speed šŸ“š Explanation: A Scalar quantity is one that has only magnitude (size) but no specific direction. Speed is a scalar because it only describes how fast an object is moving (e.g., 50 km per hrs). Vector quantities, like Velocity, Acceleration, and Force, have both magnitude and direction (e.g., 50 km per hrs North). Understanding this distinction is fundamental in physics.
