**Non-Uniform Motion**

Non-uniform motion refers to the type of motion in which an object covers unequal distances in equal intervals of time. In simple terms, when the speed of an object is not constant, it is said to be in non-uniform motion.

**Examples of Non-Uniform Motion**

Here are a few examples of non-uniform motion:

1. A car moving through a crowded city street experiences non-uniform motion as it slows down and speeds up due to traffic and road conditions.
2. A ball rolling down a hill experiences non-uniform motion as it accelerates due to gravity.
3. A person riding a bicycle and changing speed frequently encounters non-uniform motion.
4. A pendulum swinging back and forth slows down and speeds up, demonstrating non-uniform motion.

**Uniform and Non-Uniform Motion**

Uniform motion refers to the type of motion in which an object covers equal distances in equal intervals of time. It occurs when the speed of the object remains constant throughout its motion. On the other hand, non-uniform motion occurs when the speed of an object is not constant.

**Characteristics of Uniform Motion**

In uniform motion:

1. The object covers equal distances in equal intervals of time.
2. The speed of the object remains constant.
3. The object moves in a straight line.

**Characteristics of Non-Uniform Motion**

In non-uniform motion:

1. The object covers unequal distances in equal intervals of time.
2. The speed of the object is not constant.
3. The object may move in a straight line or along a curved path.

**Graphical Representation**

Uniform motion can be represented by a straight line on a distance-time graph, where the slope of the line represents the speed of the object. On the other hand, non-uniform motion is represented by a curved line on the graph, indicating varying speeds.

**Conclusion**

In conclusion, non-uniform motion refers to the type of motion in which an object covers unequal distances in equal intervals of time. It occurs when the speed of the object is not constant. On the other hand, uniform motion occurs when an object covers equal distances in equal intervals of time, with constant speed. Understanding the difference between these two types of motion is essential in the study of physics and motion.
