What calculation is represented by 'Азатр=FS'?

This formula represents the total work done (or work input) to move the block up the inclined plane. 'Азатр' stands for total work, 'F' is the applied force pulling the block, and 'S' is the distance over which the force is applied (the length of the inclined plane). The unit for work is Joules (Дж).
