The impulsive motion of a sphere along a plane wall in a viscous fluid is treated on the basis of the Stokes approximation. A solution to the equations for unsteady motion is obtained by applying the Laplace transformation with respect to time to the basic equations. Results obtained to a first approximation for the drag and the torque acting on the sphere show that: 1. A sphere which starts impulsively to translate parallel to a wall experiences a drag and a torque about its center. 2. When a sphere begins impulsively to rotate near a wall, it experiences a drag as well as a torque. 3. The additional contribution to drag or torque due to unsteadinessof motion decreases with time as t^<-3/2> (t is the time) in the presence of a wall.
