A moment and a torque are similar concepts, but they have different meanings and units of measurement.
A moment is a measure of the ability of a force to cause rotation around an axis or a pivot point. Moments are expressed in newton-meters or pound-feet and are often referred to as "moment of force" or "torque." Moments can be positive or negative, depending on the direction of the force and the direction of rotation.
Torque, on the other hand, is a specific type of moment that is used to describe twisting forces that cause rotation. Torque is often expressed in newton-meters or pound-feet and is measured by multiplying the force applied by its distance from the axis of rotation. Torque is always positive, regardless of the direction of rotation.
In summary, while moments and torque are similar concepts that describe the ability of a force to cause rotation, torque specifically refers to twisting forces that cause rotation, while a moment can refer to any type of force that causes rotation.
