**Motion of the athletes in a long distance race**
The motion of the athletes in a long distance race can be considered as non-uniform. To understand why, let's analyze the characteristics of uniform and non-uniform motion.
**Uniform Motion**
Uniform motion refers to the movement of an object at a constant speed in a straight line. In this type of motion, the object covers equal distances in equal intervals of time. The velocity remains constant throughout, and there is no change in direction.
**Non-Uniform Motion**
Non-uniform motion, on the other hand, involves the movement of an object with varying speed or changing direction. In this type of motion, the object does not cover equal distances in equal intervals of time. The velocity is not constant and may change over time.
**Analysis of the athletes' motion in the race**
In the given scenario, the athletes are expected to take four rounds of a track, starting and finishing at the same line. This implies that the motion includes both changes in direction and changes in speed.
1. **Changes in direction:** The fact that the athletes need to complete multiple rounds indicates that they have to turn at the end of each lap to continue running in the opposite direction. These changes in direction imply non-uniform motion since the athletes are not moving in a straight line.
2. **Changes in speed:** Another aspect that suggests non-uniform motion is the possibility of athletes changing their speed throughout the race. Different factors such as fatigue, strategies, or competitive situations can cause athletes to vary their speed during different stages of the race. For example, they may start with a faster pace, slow down during the middle rounds, and then sprint towards the finish line. These changes in speed further indicate non-uniform motion.
Considering both the changes in direction and the potential variations in speed, it is evident that the motion of the athletes in a long distance race is non-uniform. They move in a circular path, changing direction at the end of each lap, and their speed can fluctuate throughout the race.
