प्रश्न
What is the difference between uniform linear motion and uniform circular motion ? Explain with examples.
उत्तर
In uniform linear motion, the speed and direction of motion is fixed and so, it is not accelerated. Example- A car running on a straight road.
In uniform circular motion, the speed is constant but the direction of motion changes continuously and hence, it is accelerated.
Example- Motion of earth around the sun.
