The pound-force is a non-SI unit of force or weight (properly abbreviated "lbf" or "lbf"). The pound-force is equal to a mass of one pound multiplied by the standard acceleration due to gravity on Earth (which is defined as exactly 9.806 65 m/s², or exactly 196,133/6096 ft/s...
1 kilogram force (kgf) was the force of gravity, which is pushing a mass of 1 kg at one place in the world on the ground; calculated according to Newton's law force = mass × acceleration. Since the acceleration is dependent on the location, the weight force is varying. Usually, howev...
(This is particularly important in any problem involving mechanical vibrations, as we will see when we come to Chapter 7.) This takes us to the magic number of 9.807 (m s–2), which is an agreed “standard” value of the acceleration due to gravity at the Earth's surface (referred to...
The dynamic energy in a falling object at the impact moment when it hits the ground can be calculated as E = Fweight h = m ag h (4) where Fweight = force due to gravity - or weight (N, lbf) ag = acceleration of gravity (9.81 m/s2, 32.17405 ft/s2) h = falling height...

Hydrostatic pressure is the pressure of fluid caused by the force of gravity. It is an important factor not only in engineering and physics, but also in medicine. For example, blood pressure is the hydrostatic pressure of blood on the blood vessel walls. It usually refers to arterial pressure...
One newton is the force equal to the weight of an average apple with a mass of 102 g. An object with a mass of one kilogram, e.g., 1 kg of sugar will weigh ~9.81 newtons on the surface of the Earth. Again, in Earth gravity, 1 kN = 102 kg = 225 lbs. 1-ton car will weig...
Gravity is a non-contact force pulling objects towards the earth. 1 Torque Torque is a measure of rotational force. The torque applied to the lug nut allowed the mechanic to remove the tire. 3 Force In physics, a force is any influence that, when unopposed, will change the motion of an...
