Expert Solution & Answer
To determine
To find whether there is any acceleration for the given case.
Answer to Problem 1CQ
No. There is a presence of acceleration, which is called as centripetal acceleration.
Explanation of Solution
Consider any object moving in a circle at a constant speed. The motion obtained by that object is called as uniform circular motion. To obtain such a motion, acceleration must be given in the direction of the center of the circle.
This kind of acceleration is called as centripetal acceleration, which acts towards the center.
Conclusion:
Thus, there is an existence of acceleration in the given case.
