Not necessarily. A net force could be zero. An unbalanced force allows you to stand up from a chair.

An empty office chair is at rest on the floor Consider the following forces Gravity Upward force exerted by the floor A net downward force exerted by air What forces are acting on the office chair?
All three of the forces are acting on the office chair.
What can you say about an object at rest pulled in opposite directions by unequal forces?
An object at rest pulled in opposite directions by unequal forces will start to move in the direction of the net force. For example, if I have a chair, and I'm pushing with 10 newtons to the right, and my sister is pushing 5 newtons to the left, the net force is 5 newtons to the right. Therefore, I win, and the chair moves to the right, in the direction of the net force.
What Combination of all of the force acting on an object?
This would be known as the net-force.
Inertia will not be affected when this type of force is zero.?
Inertia will not be affected when "net" or "net force" is zero.
What amount of work is don't on a chair pushed 9m across a floor by a horizontal 30-N net force?
Work = (force) x (distance) = 30 x 9 = 270 joules
Why doesn't the force you exert when sitting on a chair cause the chair to move?
because the floor exerts the same amount of force which means the net force is balanced causing it not to move
When you sit on a chair a resultant force on you is?
The Answer is (A) - Zero Explanation: When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces.
An empty office chair is at rest on the floor Consider the following forces Gravity Upward force exerted by the floor A net downward force exerted by air What forces are acting on the office chair?
All three of the forces are acting on the office chair.
Do all action-reaction forces produce motion?
Some do and some don't. In the case of someone sitting on a chair, they exert a downward force on the chair due to their weight. The chair exerts an equal and opposite reaction force on them but, since this upward force acting on the person is equal to their weight, the net force is zero and the person does not accelerate. However, consider now if the person pushed themselves up off the chair with their hands. They are now exerting an additional force on the chair with their arms along with the force due to their weight. The chair will exert a reaction force on the person that is equal and opposite to the combined downward force due to the person's weight and their arms pushing. Since it is equal to the weight plus the pushing force of the arms, it will be greater than the downward force on the person due to their weight and a net upward force will be produced, accelerating the person upwards.
What happens when the forces aren't balanced while sitting on a chair?
Whenever there are unbalanced forces, an object will accelerate. If you are sitting on a chair and there are unbalanced forces, you will start to move.
What can you say about an object at rest pulled in opposite directions by unequal forces?
An object at rest pulled in opposite directions by unequal forces will start to move in the direction of the net force. For example, if I have a chair, and I'm pushing with 10 newtons to the right, and my sister is pushing 5 newtons to the left, the net force is 5 newtons to the right. Therefore, I win, and the chair moves to the right, in the direction of the net force.
When you sit in a chair what force does it exert against you?
A force exactly equal to the weight of your posterior against the chair. You know positively that the forces there must exactly cancel and add to zero, otherwise a net, non-zero force would be present, and your butt would accelerate.
What Combination of all of the force acting on an object?
This would be known as the net-force.
Inertia will not be affected when this type of force is zero.?
Inertia will not be affected when "net" or "net force" is zero.
What amount of work is don't on a chair pushed 9m across a floor by a horizontal 30-N net force?
Work = (force) x (distance) = 30 x 9 = 270 joules
What is sum of the forces that are acting on an object?
Net Force, Or Net Resultant Force, or Resultant force
What are the sum of all forces acting on an object?
I'd call it the resultant, but "net force" is a good name too.
