alleryStart learning →The second condition for equilibrium involves avoiding:
AAccelerated rotation
BAny straight motion
CAll contact forces
DAny change in mass
Answer & Solution
Correct answer: A. Accelerated rotation
1. The two conditions cover two kinds of acceleration.
2. The second condition necessary to achieve equilibrium involves torque.
3. It involves avoiding accelerated rotation.
4. That means maintaining a constant angular velocity.
