In a system where torque equals zero, what can be concluded about acceleration?

In a system where torque equals zero, it indicates that there is no net rotational force acting on the object. According to Newton's laws, particularly the second law of motion, if an object is not experiencing a net force, then its state of motion will not change. This means that if the object was initially at rest, it will remain at rest, and if it was moving at a constant velocity, it will continue to do so.

When analyzing rotational motion, torque is crucial for understanding how an object's angular velocity changes over time. If the torque is zero, there is no angular acceleration influencing the system. Consequently, a state of zero torque implies that the angular acceleration must also be zero, which indicates that any angular velocity remains constant, leading to the conclusion that the acceleration is zero.

Therefore, the conclusion that can be drawn regarding acceleration in a system with zero torque is that the acceleration must be zero. This satisfies the conditions for both translational motion (if applicable) and rotational motion, based on the laws of physics governing motion and force.
