Question
Write a short note on uniform circular motion.
✓
Answer
When a body moves in a circle, it is called circular motion. When the velocity of an object changes, we say that the object is accelerating. The change in the velocity could be due to change in its magnitude or the direction of the motion or both.
If the athlete is running along a hexagonal shaped path $A B C D E F$, the athlete will have to change his direction six times while he completes one round. If the athlete moves with a velocity of constant magnitude along the circular path, the only change in his velocity is due to the change in the direction of motion.
The motion of the athlete moving along a circular path is an example of an accelerated motion.
The circumference of a circle of radius $r$ is given by $2 \pi r$. If the athlete takes $t$ seconds to go once around the circular path of radius r , the velocity v is given by
$
v=\frac{2 \pi r}{i}
$
