The forces included on a free-body diagram typically include gravity, normal force, friction, tension, and any other external forces acting on the object. These forces are depicted as vectors to show their magnitudes and directions in relation to the object.
Newton's first law describes something special that results from the sum of all the external forces (including gravity) on an object. The forces exerted by the object on other things or on itself are irrelevant to that result, and so the free body diagram used to calculate that result gives the correct result even though we completely neglect forces exerted by the body. Why is Newton's first law important? That's a different question (see below).
Forces can be shown in a diagram using arrows. The length and direction of the arrows represent the magnitude and direction of the force, respectively. You can label the arrows with the type of force and its value if known.
The most common forces shown in a free body diagram are gravity (weight), normal force, tension, friction, and applied forces. These forces represent the interactions acting on an object in a given situation.
To identify errors in a diagram and draw a correct free-body diagram, you need to look for missing or incorrect forces acting on the object. A free-body diagram should include all forces acting on the object, such as gravity, normal force, friction, tension, and any other external forces. Make sure to accurately represent the direction and magnitude of each force in the diagram.
In a free body diagram of a roller coaster, the forces acting on it are gravity, normal force, friction, and air resistance.

carefully
On a diagram objects are usually drawn as boxes or circles and forces are usually seen as arrows. The arrows will depict the direction the force is traveling.

A pulley force diagram illustrates the forces acting on a system involving pulleys. It helps in analyzing the forces by showing the direction and magnitude of the forces exerted on the pulleys and the objects they are connected to. This diagram allows for a clearer understanding of how the forces interact within the system, aiding in the calculation of mechanical advantage and tension in the system.
A free body diagram is important in analyzing the forces on an Atwood machine because it helps to visually represent and identify all the forces acting on the system. This diagram allows for a clear understanding of the forces involved, making it easier to calculate and analyze the net force and acceleration of the system.
