What is the moment?

Merriam-Webster states that,

Moment is the product of the distance from the point to the point of application of the force and the component of the force perpendicular to the line of the distance.

In the opinion of Wikipedia,

In physics, a moment is an expression comprising the product of physical quantity and distance, and in this way, it accounts for how the physical quantity is situated or arranged.

The S.I unit for moment or moment of force is Newton-Meter (Nm).

Moment of force formula

The formula for moment of force can be expressed as:

M = F × d


M represents the moment,

F is the applied force, and

d represents the total distance from the axis.

How to calculate moment of force?

Moment of force calculator offers the easiest way to calculate moment, force, and lever arm length. Let’s see how you can calculate moment of force without using the moment calculator online.


Calculate the moment of force in an object moving with a force of 50 N at the distance of 2.5 meters from the axis.


Step 1: Identify and write down the values.

F = 50 N

d = 2.5 m

Step 2: Write down the moment formula.

M = F × d

Step 3: Place the given values in the moment of force equation and simplify it.

M = 50 × 2.5

M = 125 Nm

By using the same method and equation, you can also calculate the force and length of lever arm (distance from the axis). You can also use the moment calculator for physics numerical preparation.


How to calculate lever arm length?

Lever arm length can be calculated by using the moment equation.

M = F × d

In this equation, d represents the lever arm length. So,

d = M/F

Simply, place the values of moment and force to calculate lever arm length.

Is moment and torque the same?

Moment and torque are considered the same in physics. But, in mechanics, the moment and torque are slightly different from each other.
