The distance covered by an object in one unit of time is referred to as its:

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

Answer: (B)

The distance covered by an object in one unit of time is referred to as its speed. Speed is defined as the rate at which an object moves and signifies how much distance is traveled per unit of time, typically measured in meters per second (m/s). It is a scalar quantity, meaning it only has magnitude and no direction. When considering the other terms: velocity differs from speed in that it includes a direction component, making it a vector quantity. Acceleration refers to the rate of change of velocity over time, indicating how quickly an object is speeding up or slowing down. Displacement measures the shortest distance from the initial position to the final position and also accounts for direction. In summary, speed is specifically concerned with the distance traveled in a given timeframe, solidifying its role as the correct answer.
