1. the sum of all forces acting on an object is called the

Explanation:

• For question 11: When all forces on an object are balanced, the object is in a state where there is no net acceleration. This state is defined as equilibrium.
• For question 12: The normal force is the perpendicular force that a surface exerts on an object pressing against it.
• For question 13: A free - body diagram is specifically used to represent all the forces acting on an object.
• For question 14: The net force is the vector sum of all the forces acting on an object.

Answer:

1. equilibrium
2. normal force
3. free - body diagram
4. net force
