What characterizes non-uniform speed?

• A. The body travels equal distances in equal intervals of time.
• B. The body travels unequal distances in equal intervals of time.
• C. The body moves with a constant speed.
• D. The body is accelerating uniformly.

Answer: (B)

Non-uniform speed is characterized by the condition where a body travels unequal distances during equal intervals of time. This means that as time progresses, the distance covered in each time segment varies, indicating that the speed is changing. In contrast, constant speed would imply that the body covers equal distances in equal time intervals; thus, this would not represent non-uniform speed. The concept of non-uniform speed often connects to scenarios where the velocity of the moving object is not constant, suggesting that there could be acceleration or deceleration involved, which further emphasizes the variability in speed over time. Therefore, when a body is said to have non-uniform speed, it inherently indicates that the distances covered in each time interval differ, confirming the correct choice.
