# How is the work of a changing force that acts on a moving material point calculated? If it is required to calculate the work of a force that changes over time, then the displacement of a material point is divided into small enough displacements so that at each of these displacements the force modulus and the angle between the force and displacement vectors can be considered constant.Then, the work is calculated at each of these displacements and find the amount of works. 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.
