- The document discusses force and inertia in the context of a ball rolling on a surface. - When a ball rolls on a surface, applying force to it from outside can cause an acceleration. The force acting opposite to the applied force is called frictional force. - Frictional force depends on factors like the mass of the ball and surface, and the contact between them. It follows the formula F=ma, where F is frictional force, m is mass, and a is acceleration.
