Laws used for determining the resultant of vectors are mathematical rules that help calculate the combined effect of two or more vectors.
Here's a simple explanation of the three main laws:
Triangular Law of Vector:
This law says that if you have two vectors, you can visualize them as sides of a triangle and the resultant of the two vectors is equal to the third side of that triangle.
Parallelogram Law of Vector:
This law says that if you have two vectors, you can visualize them as sides of a parallelogram and the resultant of the two vectors is equal to the diagonal of that parallelogram.
Polygon Law of Vector:
This law is an extension of the parallelogram law, and it says that if you have multiple vectors, you can visualize them as sides of a polygon and the resultant of all the vectors is equal to the last side of the polygon.
