Question

Define Newton (the S.I. unit of force).

Answer 1

Hint: According to Newton’s second law of motion the force exerted on an object is equal to the product of mass and acceleration. We can calculate the system's international unit of force just by substituting the S.I unit of mass and acceleration. That is, derived from the name of Isaac Newton.

Complete step by step answer:
Newton is the unit of force. That is, in other words we can say that Newton is the system international unit of force. Thus we can define one Newton as the product of one kilogram mass with one metre per square second acceleration. The direction of force will be in the same direction as the acceleration. The S.I unit of force Newton is derived from the name of Isaac Newton. The Force which is the product of mass and acceleration actually defines Newton’s second law of motion. We can also define force as the rate of change of momentum according to Newton’s second law. The Newton is represented by the uppercase symbol N.
Thus we can define Newton’s second law as the force exerted on an object is equal to the product of mass and acceleration.
$$F=ma$$
Where, F is the exerted on an object, m is the mass of the object and a is the acceleration produced by the object.
In the above equation we can define m as the proportionality constant when force is directly proportional to acceleration.
$$$$$$1N={\displaystyle \frac{1kgm}{s^2}}$$

Note: In earlier times there are different types of units used for measurement. Three of them are CGS, FPS and MKS units. But the internationally accepted unit for the measurement is system international or simply S.I units. In this measurement there are 7 basic units.
