In which type of motion does the distance covered change during equal time intervals?

• A. Uniform motion
• B. Non-uniform motion
• C. Straight-line motion
• D. Circular motion

Answer: (B)

The scenario described pertains to non-uniform motion, where the distance covered by an object changes during equal time intervals. This type of motion is characterized by variations in speed or direction, resulting in an inconsistent distance traveled over equal durations. In non-uniform motion, the velocity of the object is not constant; it may increase or decrease. This causes the object to cover different distances in equal time intervals. For instance, if a car accelerates, it will travel a greater distance in the second second than in the first, as its speed increases. In the case of uniform motion, an object moves at a constant speed, meaning it covers equal distances in each time interval. Straight-line motion and circular motion can be either uniform or non-uniform, depending on whether the speed is constant. However, the key defining feature of non-uniform motion is the variation in distances covered in equal time intervals, making it the correct choice in this question.
