One of the greatest sources of confusion in the Imperial (or U.S. Customary) system of measurement is that both mass and force are measured using the same unit, the pound. The differentiate between the two, we call one type of pound the pound-mass (lbm) and the other the pound-force (lbf).

The pound or pound-mass is a unit of mass used in British imperial and United States customary systems of measurement….Pound (mass)

“Lbf” refers to the gravitational force placed by a matter on the Earth’s surface, while “lb” deals with the measurement of force. A pound-force equals the product of 1 pound and the gravitational field. “Lb” and “lbf” are basically similar to each other since they both involve the same force.

Yes, unfortunately, the pound is a unit of mass or force, ie it is used as both. In trade, it has always been used as mass even though people call it weight, and is legally defined that way.

The SI unit of weight is the same as that of force: the newton (N) – a derived unit which can also be expressed in SI base units as kg⋅m/s2 (kilograms times metres per second squared). Used in this sense, the proper SI unit is the kilogram (kg).

The newton (symbol: N) is the SI unit of force. 1 Newton is equal to the amount of force required to accelerate an object at a rate of 1 metre per second, every second. One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in direction of the applied force.

The answer to what is SI unit is that it is an abbreviation of the French word Système International. The International System Of Units (SI) is the metric system that is used universally as a standard for measurements.

A force is an effort that changes the state of an object at rest or at motion. It can change an object’s direction and velocity. Force can also change the shape of an object.

It may be caused due to the attack of pathogens (virus, bacteria), lack of nutritious diet/balanced diet and lack of public health services. The disease which lasts for only a short period of time is called Acute Disease. For example: Influenza (Flu), Common cold, etc. For example: TB, Cancer, etc.

Force is defined as a push or pull acting on an object. Forces include gravity, friction, and applied force. Force causes changes in the speed or direction of motion. These changes are called acceleration.

Basically, there are two main types of forces, contact forces, and non-contact forces.

There are many examples of forces in our everyday lives:

• weight force (i.e. the weight of something)
• the force of a bat on the ball.
• the force of the hair brush on hair when it is being brushed.
• the force of your foot pushing on the pedal when you ride your bike.

Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. It is an attraction that exists between all objects, everywhere in the universe. Sir Isaac Newton (1642 — 1727) discovered that a force is required to change the speed or direction of movement of an object.

Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.

The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.
