Multiple Choice
In the context of Types of Forces & Free Body Diagrams, what best describes a force diagram (free-body diagram)?
A
A diagram that shows only the net force vector on an object, with individual forces omitted
B
A simplified sketch of an object showing all external forces acting on it as labeled vectors, typically drawn from the object’s center of mass
C
A drawing of all forces an object exerts on other objects (reaction forces), without showing forces acting on the object
D
A graph of force versus time used to calculate impulse and momentum change

Understand that a force diagram, or free-body diagram, is a tool used in physics to analyze forces acting on a single object.
Recognize that the diagram simplifies the object to a point or simple shape, often representing the object’s center of mass.
Identify that all external forces acting on the object are shown as vectors originating from the object, with each force labeled clearly.
Note that the diagram does not show forces the object exerts on others (reaction forces), nor does it show only the net force without individual forces.
Conclude that the best description of a force diagram is a simplified sketch showing all external forces acting on the object as labeled vectors, typically drawn from the object’s center of mass.
