The turning effect of a force is known as the moment of Force or Torque . It is the product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn.
Torque (also known as moment, or moment of force) is the tendency of a force to cause or change the rotational motion of a body. It is a twist or turning force on an object. Torque is calculated by multiplying force and distance. It is a vector quantity, meaning it has both a direction and a magnitude.
