Question
Circular motion ______.
- Is an accelerated motion
- Requires centripetal force
- Has the direction of velocity changing at every point
- All of the above
Hint:
In circular motion speed may be constant but its direction is never constant.
The correct answer is: All of the above
Here, the correct option will be 'd' i.e; all of the above. As we know that in a circular motion the direction of velocity changes continuously, it requires centripetal force and also it is an accelerated motion. The velocity at a point is perpendicular to the direction of force acting on the body moving in a circular path.
