Draw only the forces acting on the chosen particle and label their directions.
A force diagram represents the forces exerted on the chosen object. Include its weight, contact forces and any pulls, pushes or resistance stated in the model. Choose a positive direction. Keep velocity and acceleration arrows separate from force arrows.
A crate moving right on a horizontal surface is driven by D and resisted by F. Its weight is mg downward and its normal reaction is R upward. If it stays on the horizontal surface, its vertical acceleration is zero.
