| **A force of 200 N is applied to a stationary mass of 100 kg, while the position of the body has not changed, what is the work of the force?**

Data: m (mass of an immobile massive body) = 100 kg; F (force applied to a massive body) = 200 N.

Since the position of the body has not changed, the displacement of the massive body is equal to zero and the work of the force applied to it is equal to zero (A = F * s = 200 * 0 = 0 J). This is due to the fact that the magnitude of this force is insufficient to overcome the sliding friction force (Ffr. = Μ * m * g).

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
