Question

why we do addition of vectors and what is its use in our daily life

Answer 1

Hey there !

Suppose you have to lift up a cup of coffee from table by keeping your eyes closed.You dont know the location of cup on the table. I tell you it is at 1 arm distance away from you.

It will take you many more tries as you are not aware of direction in which cup is placed. You may end up swinging your arm in an arc to locate the cup.

Now you can easily locate the cup as you know the direction as well as magnitude of the distance of location of cup from you…Thats how we make use of vectors in real life unknowingly.

There are many more examples like computing the direction of rain, flight of bird and the list is never ending.

Hope it helps you !
