### Why is net force a vector sum?

Force is a vector, and so the sum of all forces acting on an object is a vector 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.

### 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.

### 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.

### 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).

### 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

Net force.

### Will all forces cause an object to accelerate?

Any force will do, as long as it's an unbalanced force (the sum of all forces acting on the object must not be zero).
