Difference Between Force and Rotational Torque
Lever Arm Principle
Torque (Nm) and force (N) are fundamentally different. Torque = Force × Lever Arm, so N = Nm ÷ lever arm (m). A 100 Nm torque applied at 0.5m distance produces 200N of force. At 1m, the same torque produces 100N. At 2m, only 50N. This is why longer wrenches make bolts easier to turn — the same hand force produces more torque with a longer lever arm.
Physics Formula Explanation
In physics, torque (τ) = r × F × sin(θ), where r is the lever arm length, F is the applied force, and θ is the angle between them. When the force is perpendicular (θ = 90°, sin = 1), torque is maximized: τ = r × F. Newton-meters measure rotational tendency, while newtons measure linear force.

Frequently Asked Questions
No. Newton (N) measures force, while newton meter (Nm) measures torque. Torque = Force × Distance, so 1 Nm = 1 N applied at 1 meter distance.
Divide Nm by the distance in meters: N = Nm ÷ distance. For example, 100 Nm applied at 0.5 meters = 200 N of force.
Torque is a rotational force — the twisting power applied to turn something. It equals force multiplied by the length of the lever arm.
