Connected Objects and Centripetal Force

Special Cases of Motion (with Friction):

• When acceleration is downwards on an inclined plane, the net force is given by $(mg \sin \theta - \mu_k mg \cos \theta) = ma$.

• This represents the component of gravity pulling the object down the plane minus the kinetic friction force opposing the motion. This assumes the block is attempting to slide down while potentially connected to another system (implied by
