Why not ? Take four big guys shaped like barrels, who can push a car uphill with one hand. Now put the car on a flat parking lot and spread the four guys around it, with one guy in the back pushing forward, one in the front pushing backward, one on the left pushing right, and one guy on the right pushing left. Where will the car go ? Nowhere. Even in neutral with the parking brake off. If you remember to include the directionof each force, then all the forces on the car add up to zero.

What quantities sum to zero when a system is in equilibrium?
For equilibrium, two conditions have to be met:* The sum (vector sum) of all forces acting on the object has to be zero (otherwise, it will start to accelerate). * The sum of all torques acting on the object has to be zero (otherwise, it will start to rotate).
What is the expression for equilibrium?
the sum of all forces acting on an object should be equal to zero the sum of all forces acting on an object should be equal to zero
Why are balenced and unbalenced forces different?
"Balanced" means that the sum of all forces acting on an object is zero."Unbalanced" means that the sum of all such forces is NOT zero. (The "sum" refers to a vector sum.) An unbalanced force will result in an acceleration; a balanced force won't.
When the sum of two opposing forces is zero?
The forces are balanced when the sum of two opposing forces is zero.
Explain the difference between balanced and unbalanced forces?
The vector sum of all of the individual forces in a balanced group of forces is zero. The vector sum of all of the individual forces in an unbalanced group of forces isn't.
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.
When the net forces acting on an object sum to zero then the object is acceleration?
When the net forces acting on an object sum to zero then the object's acceleration is zero.

What is forces equilibrium at a point?
When the (vector) sum of all forces equal zero.
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 is the difference between balanced and unbalaced forces?
The vector sum of a group of forces is zero. The vector sum of a group of forces isn't zero.
Explain the difference between balanced and unbalanced forces?
The vector sum of all of the individual forces in a balanced group of forces is zero. The vector sum of all of the individual forces in an unbalanced group of forces isn't.
Definition of balanced forces in physics?
Two or more forces are balanced if their vector sum is zero. That means they all cancel each other out, and the total result is just as if there were no forces at all.
What is unbalance?
That simply means that the sum (vector sum) of all forces acting on an object is not equal to zero.
