Question

multiple - choice question
what is a free body diagram?
a picture showing all the forces acting on an object.
a picture showing an object experiencing freefall.
a picture picture showing applied and frictional forces.

Explanation:

A free - body diagram is a visual representation used in physics (a sub - field of Natural Science). It isolates an object from its surroundings and shows all the forces acting on that object. The option "A picture showing an object experiencing freefall" is incorrect because free - body diagrams are not limited to free - fall situations. The option "A picture showing applied and frictional forces" is also incorrect as free - body diagrams show all forces (not just applied and frictional), such as gravitational, normal, tension etc.

Answer:

A. A picture showing all the forces acting on an object.
