The physics
A free-body diagram shows only the forces on one chosen body. For every arrow, you must name what gives it.
Start with the weight. It is always there, straight down.
Then go round the body. Each thing that touches it can push, rub or pull. A surface pushes out (the normal force) or rubs (friction). A string or a spring pulls.
From the ground, there is no “force of motion”. There is no centrifugal force and no pseudo force either. For a system, leave out the forces its parts put on each other.
