Understanding Moment of Force (Torque)

Moment of force, commonly known as torque (τ), is a measure of the rotational force applied to an object. It quantifies the tendency of a force to cause or change the rotational motion of an object. Torque is calculated by multiplying the force applied by the perpendicular distance from the axis of rotation to the line of action of the force.

Formula: Torque (τ) = Force (F) × Distance (r) (where F is perpendicular to r)

The SI unit for moment of force is the Newton meter (N·m).
