Force	Stress
1] A force is a push or pull upon an object resulting from the objects interaction.	1] When anybody is subjected to external loading, then elements from body will try to oppose that force i.e. internal resistance offered by elements from body is known as stress.
2] Its unit is Newton (N) $1N = 1kg – m/s^2$	2] Its unit is $N/m^2$
3] $Force = mass \times acceleration.$	3] $Stress = \frac{Resisting \ force}{Area}$
4] Force can be of several types such as frictional force, Gravitational force, Tension force, etc.	4] Stress can be of two types such as Normal stress and Shear stress.(Basic conversion for calculation): $1Kpa = 10^3 N/m^2$ $1 Mpa = 10^6 N/m^2 = 1 N/mm^2$ $1 Gpa = 10^9 N/m^2 = 10^3 N/mm^2$
