# mam how do you solve problems based on using vectors in this topic and coming topics? is there any other method to solve this type of problems because i don`t understand vectors?

The main point while considering the vectors in being able to imagine the defferent components of a vector in different direction/dimensions as once it is done, we can apply usual arithematics in each dimension/ direction independently.

Also while taking cross or scalar products of two vectors we must know the difference and meaning of each of them.
Like scalar product of a vector gives a scalar and basically gives the length of the projection of one vector on other and cross product gives a vector which is mutually perpendicular to both the vectors.
