A ball is whirled in a circle by attaching it to a fixed point with a string. Is there an angular rotation of the ball about its center? If yes, is this angular velocity equal to the angular velocity of the ball about the fixed point?
Answers
Answer ⇒ Yes, there is the Angular rotation of the ball about its centre.
The Angular Velocity of the ball about its center is equal to the angular velocity of the ball about the fixed point.
Explanation ⇒ Yes the ball has an angular rotation about its center. If we will be noticing the position of the point on the ball where it is tied with the string, we can easily see that it is moving about its center as its position changes.
This point again comes to the same position when the ball makes a complete revolution around the fixed point.
Thus the ball rotates about its center through 360° in the same time in which the ball revolves through 360° around the fixed point.
Hence the angular velocity of the ball about its center is equal to the angular velocity of the ball about the fixed point.
