How is distance covered per unit of time defined?

• A. Acceleration
• B. Displacement
• C. Velocity
• D. Speed

Answer: (D)

Distance covered per unit of time is defined as speed. This concept refers to how quickly an object moves, indicating the rate at which distance is traveled over time. Speed is a scalar quantity, meaning it has magnitude (how fast something is moving) but no directional component. For example, if a car travels 60 kilometers in one hour, it has a speed of 60 kilometers per hour. This definition focuses solely on the total distance traveled, irrespective of any direction or changes in position. Thus, speed is a fundamental concept in physics that helps quantify motion and is essential for understanding various physical phenomena.
