This is the difference between Mass and Weight. 1 lb is the force required to give a mass of 1 slug an acceleration of 1 ft/ s². 1 lb is the force required to give a mass of 1/32.2 slug an acceleration of 32.2 ft/ s². W = mg. m = W/g. W/g is often substituted for m, especially in the English System. Force is in Pounds! Mass is in Slugs!

A pound-force is a unit of force, which is equal to 4.44822 N. The pound-mass (lbm) and pound-force (lbf) are related by the following expression. There is no general relationship between kilograms and pound force; kilograms measure mass and pounds force measure force. Similarly, there is no relationship between newtons and pounds mass.

where k is a constant. This formula is so important in physics that it was used to define the newton, N, the unit of force which was defined in such a way that k = 1. A force of 1 N acts when a mass of 1kg is accelerated at 1 ms-2. Inserting these values into the equation F = kma gives. 1 = k x 1 x 1 ( k = 1. Hence, F = ma. F = force (N) m ...

Because weight is proportional to the objects mass (assuming we stay on Earth), scales are sometimes calibrated in units of mass. Scales calibrated in English units almost always use force units (pounds or ounces) whereas metric scales are typically calibrated in mass units (grams or kilograms). The metric unit of force is the Newton (N).

A force of 20 N acts upon a 5 kg block. Calculate the acceleration of the object. An object of mass 300 kg is observed to accelerate at the rate of 4 m/s2. Calculate the force required to produce this acceleration. A 5 kg block is pulled across a table by a horizontal force of 40 N with a frictional force of 8 N opposing the motion.
