Question

3
which of the following best describes the information shown by a free - body diagram?
a. the friction and air resistance acting on an accelerating object
b. all of the things that surround an object
c. all of the forces acting on an object
d. the net force on a falling object

Explanation:

A free - body diagram is a graphical representation. It is used to show all the forces acting on an object. Option A only mentions two types of forces (friction and air resistance), which is not comprehensive. Option B is incorrect as it is about surroundings, not forces. Option D is about the net force on a specific (falling) object, while a free - body diagram can be for any object and shows all forces, not just the net force.

Answer:

C. All of the forces acting on an object
