Key Points

- A free-body diagram is a visual technique used to represent the forces acting on a single object.
- There are four steps on how to do it:
1. Draw a sketch of the object at the middle of the coordinate system.
2. Identify all the forces acting on the object.
3. Draw the forces as vector arrows.
4. Label the forces acting on the object using symbols.



Answer :

Final answer:

Free-body diagrams are essential in physics to analyze forces on an object accurately using vectors and dots.


Explanation:

Free-body diagrams are visual tools used to represent all forces acting on an object, depicted by a dot or small circle. Forces are drawn as vectors originating from the dot with correct directions and lengths. They are crucial in applying Newton's laws of motion for analyzing physical situations.
