Units play a great role in physics. It is used to designate the magnitude of dimension.The force is a push or a pull that acts on mass and changes its acceleration.The dimensional formula of force is
[MLT. Like all quantities it is also has units. There are ways of representing units of force. Lets see about it.^{ -2}] |

The unit of measurement of force in the metric system is the Newton, that is kilogram times meters per second square

**(kgm/s**. In US standards it is measured in pounds^{2})**(lbf)**. Like wise there are 5 units of force namely- Centimeter Gram Second unit
**(C.G.S)** - Foot Pound Second unit
**(F.P.S)** - Meter Kilogram Second unit
**(M.K.S)** - System of International unit
**(S.I)**

**Here is given the force unit based on the system**

**C.G.S system :**A**dyne**is defined as a force that acts upon a mass of 1 gram that produces an acceleration of 1 cm/s^{2}in the direction in which it acts.**F.P.S system :**When a mass of 1 pound is subjected to an acceleration of**1****ft/sec**the force applied is called^{2}**1 poundal**. It is abbreviated as pdl. One poundal is**1****lbm-ft/sec**^{2}.-
**M.K.S system :**A**Newton****(N)**is that much force which produces an acceleration of 1 cm/s^{2}in the direction in which it acts. **S.I system :**It is unit used globally. Most of the time we go for metric unit as S.I unit. Hence the S.I unit of force is**Newton****(N)**.

Force is that which is experienced when a mass being accelerated or decelerated in a certain direction. There are five ways to represent the units for force:

The Metric system is that system is commonly used as it is a easy way to express the dimension as compared to system used in US states. It called as meter-kilogram-second

**(MKS or mks)**system of units is based on three fundamental units named after meter, kilogram and second. The MKS unit is easy to work in scientific notation.

The force unit in metric system is Newton (N). It is the force that produces an acceleration of 1 kg of mass. It is abbreviated as N.

**1 N = 1 kg $\times$ 1 m/s**

^{2}**= 1000 gm $\times$ 100 cm/s**

**= 10**

^{5}gm cm/s**= 10**

^{5}dynes**Thus One Newton is that a body of mass 1 kg moving with the acceleration of 1 m/s**

^{2}. If the body is moving with an acceleration of 9.81 m/s

^{2}then the force acting on the body will be 9.81 newtons.

All systems of weighs and measures metric and non metric are linked through a network of international agreements supporting the International system of units. The SI unit was named after the two initials of the French name

The S.I unit is measured by a small agency in Paris known as

**Le Systeme International d' units**. So it can be expanded as System unit of International.The S.I unit is measured by a small agency in Paris known as

**BIPM**(Bureau International des Poids et Mesures) and is updated every few years by an international conference called**CGPM**(Conference Generale des Poids et Mesures). This is the only type of unit that is globally recognized. It can be used anywhere in science, engineering and commerce.**The S.I unit of force is Newton (N).**

A Newton unit is a standard unit we use. It was named after Isaac newton as he was the one who proposed the second law. According to newtons second law the force is given as

Here F is the Force applied

m is the mass

a is the acceleration

In dimensional analysis we have

Replace it by standard units. If mass of 1 kg is given a acceleration of 1 m/s

**F = ma**

m is the mass

a is the acceleration

In dimensional analysis we have

F = $\frac{ML}{T^2}$

Replace it by standard units. If mass of 1 kg is given a acceleration of 1 m/s

^{2}then the force is1 N = 1 kg $\frac{m}{s^2}$
