The following analysis holds while I am sitting in/on the chair:
Gravitational force -- downward
Resistance force of the chair -- upward
Sum of the forces on the seat of my pants -- Zero
Therefore neither I nor the seat of my pants is accelerated.
If it starts moving, that implies that the frictional force is less than 15 N.
because the floor exerts the same amount of force which means the net force is balanced causing it not to move
AS much as you weigh is the lbs of force that your chair exerts
Static is a force that doesn't move Dynamic force is a moving force. For instance, Static force is like being sat on a chair. Dynamic, is a moving force; Like a hurricane.
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.
If it starts moving, that implies that the frictional force is less than 15 N.
If it starts moving, that implies that the frictional force is less than 15 N.
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
because the floor exerts the same amount of force which means the net force is balanced causing it not to move
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
The force is exactly equal to the weight of the boy, provided his feet are not resting on the floor. If they are, the force between the boy and the chair is the boy's weight minus the force between his feet and the floor. Remember, in physics weight is a force due to gravity and not a property of matter (mass). The weight of the boy can be calculated from his mass (given that he is subject to the known gravity of earth) at roughly 10 Newtons per Kg.

Not necessarily. A net force could be zero. An unbalanced force allows you to stand up from a chair.
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
Assuming that the seat of the chair is horizontal, and you an penis d the chair are stationary, the key forces here are your weight, which is acting vertically downwards on to the chair, and an equal reaction force, or normal contact force, of the chair acting on you. This force acts vertically upwards. You could also include the forces of the air acting on you and vice versa, but this is probably not what you're after.
