When is the resultant force said to be balanced?

The resultant force acting upon the body should be equal to zero. There are two terms which we must be very much familiar with while studying balanced forces:
1. Gravity :
Gravity is the force which is exerted by earth on bodies and objects. It tends to pull the objects and bodies towards the earth.
Example: To hold up the bag of vegetables the force of pull exerted on it must balance the force of gravitation exerted by the earth surface.
2. Friction :
Friction is the force which opposes the motion of two bodies in contact with each other. In other words friction acts between two bodies in contact.
Example: Imagine pushing a heavy bucket full of water but it's not moving. This is because the force of friction acting in the opposite direction of the motion of the bucket balances out the force of push exerted by you.
3. Free body diagram :
The diagrammatic representation of all the forces acting upon the object in action is called the free body representation of the object. Free body diagram are useful for determining the net force or the resultant force acting upon the body as well as determining easily the nature of forces acting upon the body viz. balanced force or unbalanced force.
