Force is an influence that will cause an object to change in some way. It is something you apply to an object.
It may change its properties, such as velocity (speed/direction) or, if it is immoveable, its shape.
An object at rest, that is having no forces applied to it, will remain in its natural state. If you wish to change its properties, then you apply forces.
Force requires energy. You cannot just have a force acting on an object to move it from its natural state without applying energy.
If the energy runs out, the object will return to its natural resting state.
If you apply too much force, the object will break.
These are some of the problems facing engineers.
The Euro is an object.
