Question

Can uniform circular motion be called as accelerated. Why

Answer 1

Accelerating objects are objects which are changing their velocity - either the speed (i.e., magnitude of the velocity vector) or the direction. An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction.

Answer 2

Hey mate!

Answer:

___________________________________________________________

⇒ We know that in a uniform circular motion, the speed of a moving object remains constant but velocity of the object is continuously changing due to the change in its direction of motion.

⇒ Lets take an example, an athlete is running along a rectangle at a constant speed. When he reaches the corner, he quickly changes his direction of motion. In order for the complete round around the rectangular track, he has to change his direction of motion four times.

⇒ Same while running along a circular track with uniform speed, the athlete has to continuously change his direction of motion.

⇒ As velocity is a vector having a magnitude as well as a sense of direction and we know that, for a uniform circular motion, the direction of motion is continuously changing, hence in uniform circular motion, the velocity of the object is also changing. And we know that change in velocity is acceleration.

⇒ Therefore, we conclude that, uniform circular motion is an accelerated motion.
