alleryStart learning →Angular acceleration is defined as the rate of change of:
AAngular velocity
BAngular position
CLinear momentum
DRotational inertia
Answer & Solution
Correct answer: A. Angular velocity
1. Every rotational quantity mirrors a translational one.
2. Linear acceleration is the rate of change of linear velocity.
3. Angular acceleration is defined as the rate of change of angular velocity.
4. Angular position, velocity and acceleration are the three rotational quantities defined in turn.
