Which of these would you include in a free body diagram of a coin sitting on a table? question 2 options: a)the forces of the coin pushing down on the table b)the force of gravity (weight) acting on the coin c)the room, to depict the physical setting d)the table

You should include the a)the forces of the coin pushing down on the table

B)the force of gravity (weight) acting on the coin

Explanation:

The free-body diagram of an object includes all the forces acting on the object itself, while does NOT include forces acting on other objects.

Therefore, the free-body diagram of the coin sitting on the table should include ONLY the forces acting on the coin.

Let's now analyze each option:

A)the forces of the coin pushing down on the table  --> NO. In fact, this force is exerted on the table, not on the coin, so this force should not be included in the free-body diagram of the coin.

B)the force of gravity (weight) acting on the coin  --> YES. This force is acting on the coin, so it should be included.

C)the room, to depict the physical setting   --> NO. The room is not a force, so it should not be included.

D)the table  --> NO. The table is not a force, so it should not be included.

Therefore, the only correct option is B.
