A moment of force, also known as torque, is the measure of the tendency of a force to rotate an object about an axis.
The moment of force is calculated by multiplying the magnitude of the force by the perpendicular distance from the axis of rotation to the line of action of the force.
The SI unit for moment of force is Newton-meter (N*m), while the imperial unit is pound-foot (lb*ft).
A force is a push or pull that causes an object to move, while a moment of force is the measure of the tendency of a force to rotate an object about an axis. In other words, a moment of force causes an object to rotate, while a force causes an object to translate.
Moment of force is used in various applications, such as in engineering to design structures that can withstand rotational forces, in sports to enhance performance and prevent injury, and in everyday activities like opening a door or using a wrench.
