Difference Between Torque and Moment

Difference Between Torque and Moment

What is Torque?

Torque is the measure of force that causes an object to rotate about an axes. Just like how force causes an object to accelerate i linear kinematics, torque is what causes an object to acquire angular acceleration.

What is Moment?

In physics, moment of force is a measure of its tendency to cause a body to rotate about a specific point or axis.

Difference Between Torque and Moment

Torque vs Moment
Torque Moment
It is the measurement of the turning force of an object It is the measurement of the perpendicular distance from the point of rotation to the force’s line of action
The symbol of torque is
\(\begin{array}{l}\tau\end{array} \)
and SI unit is Nm/revolution
The symbol of the moment is M and SI unit if NM
It is a movement-related force It is a static force
Torque is used to measure the coupling The moment is not used for this purpose
It is used where there is an availability of a pivot and rotation It is produced by any lateral force and used in non-rotational events
It is referred to the nature of the force to rotate the object in a pivot. It is referred to the nature of the force to move the object.
