Question

Define 1 newton and derive an expression for force

Answer 1

 A newton (N) is the international unit of measure for force. One newton is equal to 1 kilogram meter per second squared. In plain English, 1 newton of force is the force required to accelerate an object with a mass of 1 kilogram 1 meter per second per second.

Answer 2

$\huge\textbf{Answer}$


» 1 Newton

We know that

F = ma

m = 1 kg

a = 1 m/s²

F = ma

= 1 kg m/s²

Thus, the force is said to be 1 N. If it produces an acceleration of 1 m/s² in a body of mass 1 kg.


» Expression for force

F $\alpha$ dP/dt

F = k dP/dt

F = k d(mv)/dt

F = k m d(v)/dt

F = k ma

Here; k = 1

F = ma
