Answer
Non-uniform motion is a type of motion in which an object does not travel equal distances in equal intervals of time. This means the speed of the object keeps changing as it moves. The motion can be accelerated (speeding up) or decelerated (slowing down).
This type of motion is irregular and can happen due to various factors like changes in force, resistance, or obstacles in the path.
Characteristics of Non-uniform Motion:
- The speed is not constant.
- The motion may be in a straight line or along a curved path.
- Acceleration may be present.
Example:
- A bus traveling on a crowded city road — it slows down at traffic lights, speeds up on empty stretches, and stops for passengers.
- A ball rolling down a slope — it gains speed as it moves due to gravity.
