When an object moves through a fluid, the fluid exerts a viscous force F on the object that tends to slow it down. For a small sphere of radius R, moving slowly with a speed v, the magnitude of the viscous force is given by Stokes, law, F = 6πηRv, where η is the viscosity of the fluid.

Any object moving in a fluid experiences a drag or viscous force opposing its motion. Assume the object is spherical and the flow around it is laminar. For an object of radius 0.25m moving in honey at 70F (viscosity 20 Pa.s), what is the drag force at a speed of 0.1 m/s? If the object is moving horizontally and at the same constant speed of 0.1 m/s, a force must be exerted on it to maintain that motion. That means...

A small solid porcelain sphere, with a mass m and radius r, is placed on the inclined section of the metal track shown below, such that its lowest point is at a height h above the bottom of the loop. The sphere is then released from rest, and it rolls on the track without slipping. In your analysis, use the approximation that the radius r of the sphere is much smaller than both the radius R of the loop and...

Consider a damped pendulum consisting of a ball of mass M and radius a suspended by a fine wire of length L below a pivot. The ball is moving through a fluid of viscosity y, and this retards its motion. It is assumed that the ball moves sufficiently slowly that Stokes law applies. Under these conditions, the equation describing the motion of the sphere is given by ML =-Mg sin 0 - 6xual, The initial conditions are 012-= 0, and...
