What information must be shown for every force in a force diagram in order to determine if the forces are balanced?

• the acceleration and force of the object before the contact
• the magnitude of the force in Newtons and the direction
• the net force
• the surface area of the object the force comes in contact with

The magnitude of the force in Newtons and the direction of each force must be shown in order to determine if the forces are balanced. Additionally, the net force, which is the vector sum of all the forces acting on an object, must also be shown. The information about the acceleration and force of the object before the contact and the surface area of the object the force comes in contact with are not necessary to determine if the forces are balanced.
