What force is called the resultant? Does a resultant always exist? Give examples.

A force acting on a rigid body is called the resultant of all forces acting on this body if it exerts the same mechanical effect on the body as all these forces acting simultaneously. The resultant is not always, for example, if a pair of forces acts on the person.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
