Question

11. What remains constant in uniform
circular motion?

Answer 1

Explanation:

Since the body describes circular motion, its distance from the axis of rotation remains constant at all times. Though the body's speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body's speed and its direction of travel.

Answer 2

$\huge\underline{ \mathbb\red{❥A} \green{n}\mathbb\blue{S} \purple{w} \mathbb \orange{E}\pink{r}}\:$

In a uniform circular motion the direction of motion keeps on changing with the revolution. With the number of revolution displacement from the initial point to the final point also changes. As both these factors changes velocity also changes. But in that uniform circular motion what remains constant is speed.
