Indicate the forces acting on a ball falling in a viscous liquid.

Several forces act on this ball at once. This is the force of gravity, which pulls the ball to the bottom, the Archimedean force that pushes it out of the water, and the friction force, which is also the resistance force that acts on the ball from the side of the liquid and is directed against the movement of the ball. In this case, the friction force can be calculated according to the so-called Stokes law (English mathematician and physicist of the 19th century, who studied the hydrodynamics of a viscous fluid). This law allows you to determine the rate of formation of sediments – particles of silt, gel, foam, fog droplets and other small particles (mainly colloidal particles).
