Understanding the Motion of the Boy
The situation describes a boy walking around a circular track at a constant speed of 0.5 km/min. To determine the type of motion, we need to analyze the definitions of uniform and non-uniform motion.
Uniform Motion
- Definition: Uniform motion occurs when an object travels equal distances in equal intervals of time, regardless of the direction.
- In this case, the boy maintains a constant speed of 0.5 km/min.
Non-Uniform Motion
- Definition: Non-uniform motion occurs when the distance covered in equal time intervals is not constant, implying a change in speed or direction.
- Even though the speed is constant, the boy is changing direction continuously as he moves around the circular track.
Conclusion
- While the boy's speed is constant, the continuous change in direction means he is not in uniform motion.
- Therefore, the boy is performing non-uniform motion despite the constant speed.
Correct Option
- The correct answer is 2. Nonuniform motion.
This analysis highlights that constant speed alone does not determine uniform motion; the change in direction is crucial in this scenario.
