free body diagram
Isolated object forces
A free body diagram is a sketch used in physics and engineering that shows all the forces acting on a single object.
The object is drawn in isolation—"free" from its surroundings—with arrows representing forces like gravity, friction, tension, or applied pushes.
Draw a free body diagram showing the forces on the block.
These diagrams help analyze motion and equilibrium by making force relationships visible.
