The moment of a force about a point is the turning effect of that force, calculated as the product of the force's magnitude and the perpendicular distance from the point to the line of action of the force. It is a vector quantity, and its magnitude is often expressed in Newton-meters (Nm).   Key components Force (\(F\)): The magnitude of the applied force.  Perpendicular Distance (\(d\)): The shortest distance from the point to the line on which the force acts. This is also known as the lever arm or moment arm.  Formula: \(Moment=Force\times Distance\), or \(M=F\times d\).  Turning Effect: The moment of a force measures its tendency to cause an object to rotate about a pivot or axis.  Direction: The moment is a vector quantity with both magnitude and direction. It is either clockwise or counter-clockwise, and its direction is perpendicular to the plane of the force and the pivot point.
