The Pound-force (lbf) in Force

What is Pound-force (lbf)

The pound-force, abbreviated as lbf, is a unit of force in the British gravitational system of measurement. It is defined as the amount of force required to accelerate a one-pound mass at a rate of 32.17405 feet per second squared, under standard gravity conditions. This means that if you were to apply one pound of force to a one-pound object, it would cause it to accelerate at this specific rate.

In mathematical terms, the pound-force can be expressed using Newton's second law of motion as follows:

where F is force, m is mass, and a is acceleration. In the case of lbf, it represents the force that would be applied to a mass of one pound under standard gravitational conditions.
