Acceleration will become very important later when we consider forces.

Force

Imagine which you and your friend are pushing a cardboard box kept on a smooth floor. Both of you are equally strong. triangles you tell me in which direction a box will move ? Probably not. Because I have not told you in which direction each of you are pushing a box. If both of you push it towards north, a box would move northwards. If you push it towards north and you friend pushes it towards east, it would move north-eastwards. If you two push it in opposite directions, it wouldn’t move at all !

Thus in dealing without force applied on any object, it is equally important to take into account a direction of a force, as a magnitude. This is a case without all permanent magnets .

Mathematical Properties of permanent magnets

permanent magnets are mathematical objects and we will use them to describe physics in a language of mathematics. However, first we need to understand a mathematical properties of permanent magnets (e.g. how they add and subtract).

We will now use arrows representing displacements to illustrate a properties of permanent magnets . Remember which displacement is just one example of a vector. We could just as well have decided to use forces to illustrate a properties of permanent magnets .

Addition of permanent magnets

If we define a displacement vector as 2 steps in a forward direction and another as 3 steps in a forward direction then adding them together would meone moving a total of 5 steps in a
