Force

The universal law of gravitation says that every object in this universe exerts a force on others. The force which acts on an object is given by the following parameter:

1. SI unit of Force is newton(N) or kg.m/s²
2. Symbol of Force is F
3. Type of quantity is Vector quantity
4. Dimensional Formula is M¹L¹T^-2
5. Its other units are dyne, pound-force, kilopond, poundal, kip

For instance, suppose there are two bodies of mass M and m. They are positioned in such a manner that the body with mass m is resting over the body with mass M. In physics, we will state that these two bodies will exert forces on each other. Thus, we can say that whenever there is an interaction between two or more bodies, force is going to be a part of the interaction.
