प्रश्न
Clarify the difference.
Uniform and non-uniform motion.
उत्तर
| Uniform motion | Non-uniform motion |
| 1. When an object covers an equal distance in equal time intervals, it is said to be in uniform motion. | 1. When an object covers an unequal distance in an equal time interval, it is said to be in non-uniform motion. |
| 2. The distance-time graph obtained in the case of uniform motion is a straight-line graph. | 2. The distance-time graph obtained in the case of non-uniform motion can be of any shape depending on how the acceleration changes with time. |
| 3. The acceleration of uniform motion is zero. | 3. The acceleration of the non-uniform motion is not zero. |
| 4. eg: A car running on a straight road without any change in its speed. | 4. eg: A car running on a road with different speeds in different intervals of time. |
