The batter in a baseball game hits a home run. As he circles the bases, is his angular velocity positive or negative?
Definition Definition Rate of change of angular displacement. Angular velocity indicates how fast an object is rotating. It is a vector quantity and has both magnitude and direction. The magnitude of angular velocity is represented by the length of the vector and the direction of angular velocity is represented by the right-hand thumb rule. It is generally represented by ω.
Expert Solution & Answer
To determine
Whether angular velocity is positive or negative.
Answer to Problem 1CQ
The angular velocity of the player is positive.
Explanation of Solution
This solution works under the fact that, ‘rotation in counter clockwise direction is positive, but rotation in clockwise direction is negative.’
When the player takes a home run, he starts running in the clockwise direction around the field. Hence, the angular velocity that player holds is positive.
Conclusion:
Hence, the angular velocity of the player is positive.
