When a rigid body rotates about a fixed axis,all the points in the body have the same
A) tangential speed.
B) angular acceleration.
C) tangential acceleration.
D) linear displacement.
E) centripetal acceleration.

Question

Quizplus · Accepted Answer

When a rigid body rotates about a fixed axis, all the points in the body have the same angular acceleration. This is because the angular acceleration is determined solely by the torque applied to the body and the body's moment of inertia, which are constant for all points on the body. Therefore, choice B is the best answer. Choices A, C, D, and E are incorrect because they do not apply to all points in the body equally.
