Question
I. The centripetal acceleration is due to the change in the: a. direction of the force b. magnitude of the force c. magnitude of the velocity d. none Ans. 2. The value of an object's angular acceleration may be characterized in equivalent words by which of the following? a. rate of change of angular displacement b. acceleration c. velocity d. rate of change of angular velocity Ans. 3. If the turning tendency of the force is counterclockwise, the torque will be positive negative c. both positive and negative zero Ans.Explanation / Answer
Solution) (1)the centripetal acceleration is due to
Direction of force
So option (a)
(2) angular acceleration is due to rate of change of angular velocity
Option(d)
(3) for counter clockwise torque is positive
Option (a)
