What is the necessary condition for equilibrium of system of coplanar forces?
Coplanar or not, the two conditions for equilibrium are:The sum of all forces must be zeroThe sum of all torques must be zero.
What is the sum of the areas of all the surfaces of a figure called?
Just area. Since there is no available term for the sum of the areas of all surfaces of a figure, we call that area of the "irregular" figure.
What do you call the answer you get when you add?
the sum
What do you call the result of adding?
sum
What do you call the answer to an addition question?
A sum.
If an object is not accelerating what can you determint about the sum of all the orces on the object?
In that case, the sum of all forces must be zero.
What does it means if forces are balanced or unbalanced?
Balanced: the vector sum of all forces on an object is zero. Unbalanced: this sum it is not zero.
What term refers to the sum of all of the acting forces acting on an object?
I'd call it the resultant, but "net force" is a good name too.
What is forces equilibrium at a point?
When the (vector) sum of all forces equal zero.
Is the force greater than the the sum of the forces when forces are combined?
No, the magnitude of the resulting force when forces are combined is at MOST equal to the sum of forces, this is when they are all in the same direction. Else its magnitude will always be less than the sum of magnitudes of the individual forces involved (some forces will be oposing or "fighting" others).
Is the sum of all the forces acting on an object?
Net force.
What is the necessary condition for equilibrium of system of coplanar forces?
Coplanar or not, the two conditions for equilibrium are:The sum of all forces must be zeroThe sum of all torques must be zero.
How do balanced forces and unbalanced forces differ?
* Balanced: The vector sum of all forces on an object is zero. The object does not accelerate.* Unbalanced: The vector sum of all forces on an object is NOT zero, the object DOES accelerate.
What is unbalance?
That simply means that the sum (vector sum) of all forces acting on an object is not equal to zero.
Are there any unusual ways forces can act in pairs?
Well, apart from two forces acting on the same point, they can act at different points. Thus, even if you have forces of equal magnitude in opposite directions, the object can start to rotate.Thus, there are two conditions for an object to be in equilibrium:1. The sum of all forces is zero.2. The sum of all torques is zero.Torque is the term used for forces that can cause rotation.Well, apart from two forces acting on the same point, they can act at different points.

What term describes the vector sum of all forces acting on an object?
The term that describes the vector sum of all forces acting on an object is "net force." Net force takes into account both the magnitude and direction of all individual forces acting on the object.
What is sum of all the forces acting on an object caled?
The net force.
